AIMS AND BACKGROUND Epithelioid angiosarcoma is a rare histopathologic variant of angiosarcoma characterized by an epithelioid morphology. This subset can histologically mimic non-vascular neoplasms and impose serious challenges in reaching a correct diagnosis, especially in the context of limited tissue sampling (e.g., needle core biopsy). To improve recognition of epithelioid angiosarcoma - a...

prior walks, then one would expect less of a difference between the fast and far walks when the far test was performed fi rst. To further test this hypothesis, we revisited the order sequence of the far and the fast walks and identifi ed those who performed the fast test fi rst (n 5 8) or the far test fi rst (n 5 6) and then evaluated the difference between the fast and the far walks for the in...

this report is related to a female 7-year-old crossbreed sheep whose right eye had been protruded andswelling of upper eyelid was observed. routine enucleating was performed. histopathological evaluation ofeyelid revealed coincidence of two kinds of neoplasms. the first part was composed of multiple lobules ofsebocytes, which were detected as meibomian adenoma. the second section included infil...

INTRODUCTION Cytokeratins are important part of cytoskeleton. Cytokeratin 19 (CK 19) belongs to type I cytokeratins. Lung cancer is currently most frequently diagnosed neoplasm in males in many developed countries and in Poland. The prognosis in lung cancer remains unfavourable. The aim of this study was to evaluate the prognostic value of cytokeratin 19 expression in non-small cell lung cancer...

Cytokeratin (pan) and epithelial membrane antigen (EMA) were considered as commonly useful epithelial markers to distinguish cancer from lymphoma, but the expression of cytokeratin (pan) and EMA had also been seen in some lymphomas. Here, we presented an unusual case of anaplastic large cell lymphoma (ALCL) absence of some lymphoid markers (Including CD3, CD20, Pax-5, CD45Ro) and positive for c...

OBJECTIVE Metastatic carcinoma to subcutaneous tissue or skeletal muscle is relatively rare. The present study aimed to clarify the clinicopathological features for confirming the diagnosis as soft tissue metastasis and determining the primary site. METHODS We reviewed records of 11 patients with soft tissue metastasis who were in our institution from 1996 to 2009. RESULTS In 9 of 10 patien...

Ovarian metastasis originating from bronchioloalveolar carcinoma (BAC) has not been reported previously. We report a 63-year-old Chinese woman who was diagnosed as BAC with pleural metastasis in 1997. Four years later, she complained of vaginal bleeding, and a pelvic mass was discovered by an abdominal computerized tomography scan. Tumor debulking and total hysterectomy with bilateral salpingo-...

The myxoid variant of a diffuse malignant epithelioid mesothelioma is a rare tumor. To the best of our knowledge, only three cases of this type of mesothelioma involving the peritoneum have been reported in the literature to date. Although it is rare in the peritoneal cavity, it should be included in the differential diagnosis of the more common myxoid/mucinous abdominal lesions (e.g. mucinous ...

BACKGROUND Single soft tissue metastasis of medullary thyroid carcinoma is extremely rare. In addition, several occult medullary thyroid carcinomas with distant metastasis were reported, but undetectable primary lesion at diagnosis was also extremely rare. CASE PRESENTATION A 74-year-old man was admitted to our hospital because of a painful nodule in his left buttock for over 1 year. Needle b...

Adrenocortical adenoma is a benign neoplasm derived from cells of the adrenal cortex. The myxoid variant of this tumor is extremely rare. To our knowledge, only 23 cases of myxoid adrenocortical adenoma have been reported so far and 19 of them mentioned the pseudoglandular pattern. We reported a new case of 56-year-old Chinese female patient whose left adrenal gland was shown a neoplastic lesio...
