A 47-year-old woman is presented with pulmonary lymphangioleiomyomatosis (PLAM) involving the bilateral lung and slight pulmonary function abnormality. Computed tomography scan showed bilateral microcyst formation in the lung. Histologically, proliferating spindle shaped cells with centrilobular emphysema were main findings. Immunohistochemically, these proliferating spindle shaped cells were p...

PEComas localized in the region of falciform ligament and broad ligament are exceedingly rare. Most of them are built of spindle neoplastic cells. We report a case of epithelioid PEComa of the falciform ligament and/or broad ligament. There is only one report of such neoplasm in English-language literature. Histologically, the tumor was composed of nests of epithelioid clear cells stained posit...

We report the case of a 69-year-old patient with no significant personal urological history. The clinical and ultrasound examination revealed a prostatic gland with increased volume and homogenous appearance. After transurethral resection, multiples gray-brown-blackish prostatic chips were obtained, which could be confused with a malignant melanoma. The histological routine examination in conju...

background primary small round blue cell tumors (srbct) in sinonasal comprise histogenetically diverse entities with overlapping morphologic features. because of the limited initial biopsy tissue materials, differential diagnostic difficulties may arise, and as they have different management, exact diagnosis and classification are very important. conclusions the results of our study indicate th...

occasionally xanthomized, with marked nuclear pleomorphism, prominent nucleoli and atypical mitoses (Fig. 2), together with multinucleated giant cells. Immunohistochemistry revealed positivity for vimentin (Fig. 3A), actin, CD68, CD99 and CD10, while results for S100, HMB45, CD34, desmin, caldesmon and cytokeratins AE1/AE3 and 20 (Fig. 3B) were negative, confirming that it was an atypical fibro...

Angiomyolipoma with epithelial cysts (AMLEC), or cystic AML, is a recently characterized, distinctive cystic subtype of AML of the kidney. To date, less than two dozen of such case have been reported. Herein, we reported a prototypical case of AMLEC occurring in a 41-year-old female patient who presented with left low back pain for one month. Abdominal computed tomograph scan demonstrated a wel...
