 Abstract
 PDF
- Minimal deviation adenocarcinoma is an extremely well differentiated variant of cervical adenocarcinoma, and is frequently misdiagnosed due to its benign-looking histopathological features. A 38-year-old woman was diagnosed as having had a minimal deviation adenocarcinoma in the cervix, metastasizing to the uterine body and bilateral adnexae. She had a history of right salpingo-oophorectomy 3 years ago, and was diagnosed as having a mucinous cystadenoma. Histologically, the tumor cells were so well-differentiated that they appeared to be almost the same as those of the non-neoplastic cervical glands. Similar glands were found in both ovaries and in the left fallopian tube. PAS staining showed a negative or apical positive pattern in the endocervical-like glands.
Immunohistochemical studies for CEA, ER/PR, cytokeratin 20, and p53 were negative, but positive for cytokeratin 7. The HPV DNA microarray test was negative. Clinically, this proved to be an advanced, biologically aggressive disease.

Abstract
PDF
- Primary adenocarcinoma of the seminal vesicle is an extremely rare tumor, and its prognosis has been known to be poor. Herein, we report an adenocarcinoma of the seminal vesicle. The patient was a 50-year-old man who complained of a two-month history of terminal hematuria and lower abdominal discomfort. A pelvic magnetic resonance imaging study. Indicated a seminal vesicle cyst with focal intraluminal growth. Right seminal vesiculectomy was performed. Grossly, the seminal vesicle revealed a markedly cystic change with focal, friable, intraluminal papillary growth. The intraluminal mass showed a noninvasive adenocarcinoma with a tubular and tubulopapillary pattern, accompanied by necrosis. Immunohistochemically, the tumor was positive for cytokeratin and carcinoembryonic antigen and negative for prostate specific antigen and prostatic acid phosphatase.

Abstract
PDF
- Pulmonary aspergillomas are considered to represent saprophytic growth of hyphae within the preexisting lung cavity. Causative Aspergillus species are mostly composed of A. fumigatus and A. flavus and, occasionally, A. niger. It is difficult to identify these species using histopathologic evaluation without a culture of sputum and bronchoalveolar lavage. We recently experienced a case of pulmonary Aspergillus niger infection associated with characteristic calcium oxalate crystal formation. A large cavity contained hyphae with a typical conidial head, conidiophore, and conidia. Characteristic birefrigent calcium oxalate crystals were demonstrated in the cavity wall.

Abstract
PDF
- Farmer and Helwig coined the term cutaneous ciliated cyst in 1978 to describe specific skin cysts lined with ciliated epithelium a resembling the mucosa of the fallopian tube.
Twenty case, of cutaneous ciliated cysts have been published to date. All have been found to affect the lower limb and all patients have been women. The etiology of the cyst is as yet unknown. A 37-year-old woman had a cyst excised from the left buttock. Microscopically, the lining epithelium of the cyst wall was composed of columnar cilited cells similar to those seen in the fallopian tubes. Immunoperoxidase stainings for cytokeratin, epithelial membrane antigen and carcinoembryonic antigen were positive.
