“…Mucins (neutral and acidic) were present in the surface of tumor cells. An immunohistochemical study was performed by Dako's ENVISION method, as previously described (Terada et al 2002(Terada et al , 2004. The antibodies and the immunohistochemical results are shown in Table 1.…”

We report on a very rare case of peritoneal clear cell adenocarcinomas. A 49-year-old Japanese woman underwent hysterectomy and bilateral salpingo-oophorectomy for endometrial endometrioid adenocarcinoma grade III, which was composed of undifferentiated carcinoma cells (98%) and tubular carcinoma cells (2%). No clear cell adenocarcinoma elements were noted in this tumor. Two peritoneal cystic tumors were detected by imaging modalities around the stomach and spleen, 15 months and 21 months after the follow-up period of the endometrial carcinoma, respectively. These two tumors were surgically resected. They were cystic tumors encapsulated by fibrous capsules and showed the same morphologies. They showed proliferation of carcinoma cells arranged in solid nest, tubular, and papillary patterns. They showed clear cytoplasm positive for periodic acid-Schiff stain, hobnail cells, and occasional hyaline globules. The morphologies fulfilled the criteria of clear cell adenocarcinoma. The morphologies and immunohistochemical findings of the two peritoneal clear cell adenocarcinomas were different from those of endometrial carcinoma. We believe that the two clear cell adenocarcinomas are not metastatic lesions from the endometrial carcinoma of the uterus, and that they are primary clear cell adenocarcinomas of the peritoneum. Our case was characterized by cyst formations and encapsulation in addition to the common histological features of clear cell adenocarcinoma of the uterus and ovary. clear cell adenocarcinoma; peritoneum

“…4 Two cases have been described in the axilla. One was mistaken as a metastatic carcinoma on presentation, 2 and the other had axillary lymph node metastasis at the time of presentation. 7 To the best of our knowledge, this is the third case described in the axilla, and it did not metastasize.…”

“…A reliable diagnosis can be made by only thorough clinicoradiologic examination to rule out primary gastrointestinal and breast malignancies. 2 On immunohistochemistry examination, a primary mucinous sweat gland carcinoma is positive for cytokeratins (except CK 20), demonstrating that the tumor is histogenetically related to eccrine secretory coil. Also, absence of CK 20 contributes in differentiation of this tumor from cutaneous metastasis from the gastrointestinal tract.…”

“…Histologic resemblance of this tumor to various visceral tumors has led to confusion with metastatic lesions in its diagnosis. 1,2 To overcome this difficulty, some authors have used immunohistochemical and electron microscopic analysis. [3][4][5][6] The interest in correct identification of this tumor is because of its better prognosis compared to that of other malignant skin appendage tumors.…”

“…4 Only 2 cases have been described in the axilla. 2,7 Correct identification of primary mucinous carcinoma of skin assumes greater importance in the axilla because it closely mimics tumor arising from mammary tissue. It may not be possible to correctly identify, even with immunostaining, because both tumors may be positive for hormonal receptors.…”

Primary mucinous eccrine carcinoma is a rare malignant adnexal tumor of older patients. The histopathological features of this tumor are well-established but the cytomorphology of this neoplasm has only been documented in a few cases. The cytology and histology of this tumor may mimic metastatic mucinous carcinoma and may cause a diagnostic dilemma, especially when the tumor is located at axilla. A correct diagnosis is important because the prognosis is better than that of a metastatic mucinous carcinoma. Here we report the cytological and histological features of a case of primary cutaneous mucinous carcinoma of axilla in an elderly male patient.
