1. What Is Papillary Mesothelioma? Papillary mesothelioma, also known as well-differentiated papillary mesothelioma (WDPM), is a subtype that develops in the mesothelium but has a better prognosis compared to other mesotheliomas.
Location: Most commonly occurs in the peritoneum.
Nature: Tends to be localized and slow-growing.
2. Who Is Most at Risk for Papillary Mesothelioma? While asbestos exposure is a risk factor, papillary mesothelioma can also occur without known exposure.
Age group: Often affects younger individuals compared to other types.
Gender: More common in women than men.
3. What Are the Symptoms of Papillary Mesothelioma? Symptoms can be mild and similar to other abdominal conditions, making it harder to diagnose early.
Common symptoms: Abdominal pain, bloating, and a feeling of fullness.
Advanced signs: Fluid buildup in the abdomen (ascites).
4. How Is Papillary Mesothelioma Diagnosed? Diagnosis requires a combination of imaging tests and biopsies to distinguish it from more aggressive forms.
Imaging: Ultrasound, CT scans for detecting tumors.
Biopsy: Needed for definitive diagnosis and to assess the nature of the cells.
5. What Are the Treatment Options for Papillary Mesothelioma? Treatment is usually less aggressive due to the slow-growing nature of this mesothelioma type.
Surgery: Often used to remove localized tumors.
Observation: In cases where the disease is stable, regular monitoring may be sufficient.
6. What Is the Prognosis for Papillary Mesothelioma? The prognosis is generally favorable, with many patients having a good quality of life.
Survival rate: Better than other mesothelioma types.
Focus on management: Regular follow-ups are important to monitor any changes.
Conclusion Papillary mesothelioma is a rare and often less aggressive form of mesothelioma, offering a better prognosis than other types. With proper diagnosis and treatment, individuals can manage the condition effectively. If you experience symptoms, consult a healthcare professional for early assessment.
FAQs
Is papillary mesothelioma always benign? Not always, but it is typically considered less aggressive than other forms of mesothelioma.
Can papillary mesothelioma spread? It is less likely to spread compared to other mesothelioma types, but monitoring is still crucial.
Is papillary mesothelioma linked to asbestos exposure? While it can occur without exposure, asbestos remains a known risk factor.
How long can someone live with papillary mesothelioma? Many patients live for years with proper monitoring and treatment.
What are the surgical options for papillary mesothelioma? Surgical removal of localized tumors is common, especially when the disease is contained.
Can papillary mesothelioma recur after treatment? There is a possibility of recurrence, which is why ongoing monitoring is recommended.

Reactive Mesothelial Hyperplasia
Reactive Mesothelial Hyperplasia
Definition benign non-neoplastic proliferation of mesothelium.
Etiology RMH is often found during microscopic studies as single or multiple foci
of proliferation of peritoneum near adnexa in chronic salpingitis or endometriosis as
a stereotypic reaction on chronic inflammation and/or effusion in peritoneal cavity;
in greater omentum near the metastases of ovarian cancer; in a wall of hernial sac or
at the site of previous laparoscopy . Distinguishing RMH from malignant
mesothelioma may be difficult in some cases, especially with small biopsies, which
may cause diagnostic errors.
Histopathology RMH can have highly variable structures including solid, trabecular, tubular, papillary and tubulo-papillary patterns of growth. The lesion can be
surrounded by fibrous tissue or organizing masses of fibrin. Of note, foci of RMH
are limited by serous membrane with a gradual or sometimes abrupt transition
between normal and hyperplastic mesothelium . On cytological specimens,
reactive mesothelial cells can demonstrate nuclear atypia (ranging from moderate to
severe) and cytoplasmic vacuoles with acidic mucins, less frequently significant
clearing of cytoplasm can be appreciated. In rare cases, psammoma bodies and
rhabdomyoblast-like mesothelial cells are found . Diffuse inflammatory infiltrate, CD68-positive histiocytes, siderophages and reactive angiomatosis are often
present at foci of RMH .
The following histologic features of RMH may potentially mislead to a false
positive diagnosis of malignant mesothelioma: high cellularity, increased mitotic
activity, foci of necrosis, entrapment of single reactive mesothelial cells or even cell
clusters in organizing fibrinous effusion imitating invasion.
Differential Diagnostics Differential diagnosis spectrum of RMH is highly variable and includes MM, metastatic cancer, and serous borderline or malignant ovarian tumors.
In contrast to MM, RMH foci do not form macroscopically distinguishable nodes
on peritoneal surface. The cells do not have large cytoplasmic vacuoles. There are
no significant signs of the subjacent tissue invasion. The full spectrum of diagnostic
criteria for RMH is listed in Table 2.3.
According to recent studies it is well established that some immunohistochemical markers as ЕМА, GLUT-1, IMP-3, and р53 are ineffective in differentiation of
MM and RMH [1, 2, 26]. In particular, the immunohistochemical markers were
shown to distinguish the malignant and benign mesothelial lesions, but exclusively
from the statistic point of view [1, 2]. Therefore, abovementioned markers aren’t
applicable for an analysis of individual cases. Analysis of proliferative activity of
reactive and neoplastic cells also reveals an overlapping between both reactive and 
neoplastic lesio. Another molecular marker expressed exclusively in reactive
mesothelium is desmin . A diffuse and intensive expression of calretinin, desmin, CD44 alongside with absence of E-cadherin in most of the cases allows distinguishing between reactive mesothelium and primary or metastatic peritoneum
cancer. Despite published results it is not recommended to use any immunohistochemical stains except keratin antibodies in differentiation of benign and malignant
mesothelium.

Well-Differentiated Papillary Mesothelioma of the Peritoneum: A Retrospective Study from the RENAPE Observational Registry
Abstract
Background
Well-differentiated papillary mesothelioma of the peritoneum (WDPMP) is a rare entity. Questions regarding management are still being debated as no more than 50 cases have been reported in the literature.
Objective
We aimed to analyze the clinical, therapeutic, and prognostic data of patients with WDPMP from the RENAPE observational registry.
Patients and Methods
All patients diagnosed with WDPMP and prospectively included in the RENAPE national registry between 2010 and 2018 were also included in our study. Expert pathologists from the RENA-PATH group confirmed all cases. All clinical, therapeutic, postoperative, and prognostic data were extracted and analyzed.
Results
We report on 56 patients with a mean age of 52 years (range 21–74). WDPMP was incidentally diagnosed during imaging or surgery in 16% and 36% of patients, respectively, and an association with synchronous malignancy was found in 18% of patients. Nine lesions showed discrete signs of fatty invasion. The median Peritoneal Cancer Index was 11 (range 0–33). Eleven patients were treated with definitive excision, 4 were treated with cytoreductive surgery (CRS) only, 37 were treated with CRS and hyperthermic intraperitoneal chemotherapy (HIPEC), and 2 were treated with CRS plus HIPEC plus early postoperative intraperitoneal chemotherapy. CRS was considered to be complete in 90% of cases. One patient died postoperatively and 16 patients (31%) faced postoperative complications. The median disease-free survival was 144 months; Four patients relapsed, with a median period of 27 months. No prognostic factors could be identified.
Conclusions
Our analysis confirms the favorable prognosis of WDPMP. CRS and HIPEC could be a therapeutic option for diffuse, symptomatic, and/or recurrent disease.

Surgery Plus HIPEC Only ‘Potential for Cure’ of Peritoneal Mesothelioma
Surgery Plus HIPEC Only ‘Potential for Cure’ of Peritoneal Mesothelioma
In the case of peritoneal mesothelioma, one of the best treatment options is the combination of heated chemotherapy and cytoreductive surgery. Heated chemotherapy is called hyperthermic intraperitoneal chemotherapy (HIPEC).  A study published in the February 2018 has shown the value of this therapy for treating asbestos-related cancer. In this study, the researchers in the United Kingdom analyzed the 9.5 years of data on the patients of peritoneal mesothelioma that were treated with HIPEC and CRS.
The results of this study show that the combination of the CRS and HIPEC is very beneficial for the patients of both malignant and low-grade mesothelioma and it still has the best potential for cure.
Using CRS and HIPEC Together For Mesothelioma Treatment
Peritoneal mesothelioma has less than 20 percent of all mesothelioma diagnosis cases worldwide. Peritoneal mesothelioma is a disease that affects the lining of the abdomen. The treatment for peritoneal mesothelioma is similar to the other asbestos-related cancers. For most patients the combination of the following treatments is very promising:
HIPEC (Hyperthermic Intraperitoneal Chemotherapy)
In this treatment, a concentrated heated mesothelioma chemotherapy treatment is placed into the abdomen during the surgery. With this form of treatment, chemotherapy is directly delivered to the cancer cells in the infected area.
CRS (Cytoreductive Surgery)
This is a form of debulking surgery in which the doctor removes as much of the tumor as possible. In this surgery, the doctors try to remove all visible cancer with curative intent.
Categories of Peritoneal Mesothelioma
There are two types of peritoneal mesothelioma. One is called low-grade peritoneal mesothelioma and the other is called malignant peritoneal mesothelioma. The first category includes well-differentiated papillary mesothelioma and the cell-type multicystic mesothelioma.
In the second type of the mesothelioma, the tumors tend to be more aggressive and include biphasic, epithelioid and sarcomatoid subtypes.
Surgery Plus HIPEC is a Powerful Combination
The researchers have found the combination of the HIPEC and surgery very effective in low-grade mesothelioma. After the successful and complete cytoreduction of patients, a 100% overall survival rate is observed with low-grade peritoneal mesothelioma. Although it is not able to cure the more aggressive type of peritoneal mesothelioma it is effective in the low-grade form of peritoneal mesothelioma.
Treatments and Outcomes
In the study, there were patients that ranged in age from 21 to 73 from which 45 percent were female. About half of these patients had the low-grade disease and the other half had diffuse malignant peritoneal mesothelioma. The 26 percent of the patients had tumor debunk which means that nearly all of the tumor was removed, but not 100% of the visible tumor. The other sixty-eight percent of patients had complete tumor removal.
The remaining patients just had biopsies for the diagnosis of the tumor. Of which, 88 percent of patients with low-grade peritoneal mesothelioma that were treated with HIPEC were still alive by the end of the study. If we consider both aggressive and low-grade peritoneal mesothelioma the survival rate was about five years. Average survival rate was 97.8 months which is about 8 years, this timeframe which includes people living with the disease after it recurs.

Pathobiology of Mesothelial Tumor and Tumor-Like Lesions of the Peritoneum
Pathobiology of Mesothelial Tumor and Tumor-Like 
Lesions of the Peritoneum 
Despite the fact that the adenomatoid tumor (AT), well-differentiated papillary mesothelioma (WDPM) and malignant mesothelioma (MM) are not distinguishable from pleural analogues in their morphological, histochemical and immunohistochemical features, mesothelial tumors of the peritoneum have a number of specific  clinico-pathological and molecular features. Thus, peritoneal MM has a much lower incidence of biphasic and sarcomatoid variants of the tumor compared with pleural MM. Unlike their pleural analogues, the frequency of peritoneal AT and WDPM is much higher. In most cases, peritoneal MM, in contrast to its pleural analogue, does not demonstrate homozygous p16 deletion, but has a stable loss of immunohistochemical expression of BAP1. 
 Adenomatoid Tumor
 Definition Rare benign tumor of mesothelial origin. 
Epidemiology and Clinical Features AT can develop at any age, but most often it is observed in middle-aged and elderly women. As a rule, AT is detected accidentally during surgical procedures for other pathological lesions. The most common site of involvement is a serous lining of the fallopian tubes (AT is one of the most common benign tubal tumors) , ovaries, and intramural foci in myometrium. Fewer lesions develop in the omentum or gut mesentery .
 Gross Pathology Macroscopic examination demonstrates small dense nodules with a circumferential border situated directly under the tubal serous membrane or located intramuraly in myometrium. The tumor without a capsule but with a clear border not exceeding 2 cm in diameter is defined on the section. Unlike most leiomyomas AT cannot be extracted from the surrounding tissues (invasive growth) . Cystic transformation of individual larger nodules may develop in rare cases. Histopathology The tumor is represented by infiltrative growth of anastomosing cells with signs of mesothelial differentiation, cytoplasmic vacuoles and cytologiTable 2.1 Histopathological classification of primary mesothelial tumors of the peritoneum [WHO 2014] Histological entity Code Biological potential Adenomatoid tumor 9054/0 Benign tumor Well-differentiated papillary mesothelioma 9052/0 Benign tumor Malignant mesothelioma 9050/3 Malignant tumor epithelioid biphasic sarcomatoid K. A. Nikolay 21 cally benign round to oval nuclei without nucleoli, and extremely rare mitotic figures. Neoplastic cells are organized in typical for AT lace-like anastomizing tubular and angiomatoid structures. The latter can be represented by both slit-like spaces and signet ring-like cells with large empty vacuoles in the cytoplasm, which often makes a misleading impression of the vascular histogenesis of the neoplasm . The shape of the described structures can vary in one lesion from rounded-oval to slit-shaped with pointed edges; some of these can be cystically dilated. Homogeneous basophilic content is often observed in the lumen of glandular-like spaces. The lining of the described above structures is represented by cytologically benign cells of a cuboidal or flattened form, with minimal or undetectable mitotic activity. The second most frequent growth pattern is a solid variant of tumor, presented by layers of tumor cells with abundant eosinophilic cytoplasm . In some cases, there are well-defined papillary structures in the tumor. The above-described gland-like and vascular-like spaces are lined by cuboidal or flattened cells. Despite the benign course of disease, microscopic examination shows the infiltrative nature of growth with spreading of cells among smooth muscle fibers.
 Immunophenotype Adenomatoid tumor is diffusely positive for PanCK, CK5/6, vimentin, WT-1, calretinin, HBME-1 and thrombomodulin [4], and demonstrate negative expression of vascular markers . 
Differential Diagnosis AT should be differentiated from primary or metastatic carcinomatous lesions of the peritoneum and vascular neoplasms . Although AT, unlike cancer, has no cellular and nuclear atypia and has minimal mitotic activity, differential diagnosis requires immunohistochemical study in difficult cases, confirming mesothelial differentiation of the tumor cells and the absence of cytological signs of MM . Unlike histologically similar lipoleiomyoma, AT demonstrates a distinguishing expression of mesothelial markers. Prognosis AT has favorable prognosis.
