Because immunohistochemical features of adenoid squamous cell carcinoma (AdSCC) of the oral cavity is unclear, the author reports herein AdSCC in the gingival with an emphasis on immunohistochemical features. A 73-year-old woman presented with a left lower gingival tumor. The tumor was mildly elevated tumor measuring 1.5 x 1.5 x 0.5 cm. Dentist's diagnosis was granulation tissue, and a biopsy w...

Primary epithelioid leiomyosarcoma of uterine cervix (UC) has rarely been reported. A 90-year-old woman presented abnormal uterine bleedings. Colposcopy revealed erosions of cervix, and biopsy was taken. It showed proliferation of atypical spindle and epithelioid cells with hyperchromatic nuclei and prominent nucleoli. Mitotic figures including atypical mitosis were noted. The histological feat...

INTRODUCTION We present the immunohistochemical (IHC) analyses of a series of four kidney tumors currently classified as mucinous tubular and spindle renal cell carcinoma (WHO), a tumor with uncertain histogenesis and differentiation. Our aims were to determine an immunoprofile and to add clinical and morphological information about this rare renal carcinoma. MATERIAL AND METHODS The four tum...

Histologic and immunohistochemical features of oncocytic papillary renal cell carcinoma (RCC) have not been fully elucidated. The author herein report a case of oncocytic papillary RCC (OPRCC). A 71-year-old man with diabetes mellitus and diabetic nephropathy was found to have a small right renal tumor by CT. He had been treated with hemodialysis for chronic renal failure for 10 years. A nephre...

OBJECTIVE To evaluate the influence of surgical margin status on survival and site of recurrence in patients treated with hepatic resection for colorectal metastases. METHODS Using a multicenter database, 557 patients who underwent hepatic resection for colorectal metastases were identified. Demographics, operative data, pathologic margin status, site of recurrence (margin, other intrahepatic...

Primary sarcomatoid squamous cell carcinoma (S-SCC) of pharynx is a very rare tumor. A 77-year-old woman presented with sore throat. Laryngoscope revealed an infiltrating tumor of lower pharynx. The tumor was ulcerated and measured 3 cm × 4 cm × 3 cm. The tumor was invasive and involved the surrounding tissues. Biopsies showed sarcomatous malignant spindle cell proliferation as well as invasive...

A study was carried out on serum carcinoembryonic antigen (CEA) and alpha-feto-protein (AFP) levels, both measured by radioimmunoassay, in 88 children with malignant solid tumours and in 26 children with nonmalignant disorders, who presented during the years 1973-77. Slightly or moderately raised CEA levels were found at presentation in 11 of 66 children with malignant tumours, in 2 others with...

OBJECTIVES To describe the wide variation in presentation of cystadenomas of the liver and to delineate useful tests for diagnosis and effective surgical treatment. DESIGN A case series. SETTING A university-affiliated hospital. PATIENTS Four patients (3 women, 1 man) having cystadenoma of the liver, 2 of whom had associated mesenchymal stroma. MAIN OUTCOME MEASURES Serum and cyst fluid...

Immunocytochemical stains for three epithelial cell markers--keratin, epithelial membrane antigen (EMA) and carcinoembryonic antigen (CEA)--have been examined on paraffin-embedded material from 14 patients with nasopharyngeal carcinoma (NPC). Tumour cells staining positively for keratin were found in all cases and for EMA in eight; two tumours contained CEA-positive cells. Seven cases of Hodgki...

background and aim: salivary gland tumors classification continuously undergoes alternations, especially in the recent years. this study used immunohistochemical markers for distinguishing between polymorphous low-grade adenocarcinoma (plga) and adenocarcinoma carcinoma (adcc) which have several overlapping histological and clinical features. materials & methods: ten adcc and eight plga with fi...
