We report a new case of granular cell tumor (GCT) is a benign neoplasm in the esophagus (a rare location of which there are only described 80 cases. The tumor was diagnosed in a man aged 55 by endoscopy (asymptomatic from the esophagus point of view) during a chronic liver disease survey. The
In 500 consecutive autopsies there were 27 cases in which the livers contained PAS-positive, diastase-resistant globules within hepatocytes. On the basis of morphologic findings and immunoperoxidase staining the inclusions were separable into two groups. There were 14 (2.8%) cases in which the
Apocrine carcinoma is an uncommon variant of breast cancer. The frequency of bilaterality in patients who have apocrine carcinoma in one breast is not significantly different from that for bilateral mammary carcinomas in general, but bilateral apocrine carcinomas are very uncommon. We report on a
A case of primary malignant mesenchymal tumour of the liver occurring in an 86-year-old woman is described. This very uncommon tumour has previously only been described in children and young adults, the previous oldest being 28 years of age. The tumour was large, rapidly growing though well
Malignant müllerian mixed tumors (MMMTs) of the fallopian tube are very rare neoplasms, and we present such a case with unusual findings here. A 57-year-old Japanese woman, after she received a medical checkup, underwent salpingo-oophorectomy on the suspicion of ovarian cancer. At the time of
Although the histologic features of alveolar soft part sarcoma and granular cell tumor are typically distinctive, occasional cases show a significant morphologic overlap. Differentiating these entities is crucial because granular cell tumor is almost always benign and alveolar soft part sarcoma is
Signet-ring stromal tumor is a very rare type of ovarian neoplasm. Only ten cases of this tumor have been reported in the English literature. We report here an additional case of this type of tumor that arose from the left ovary in a 76-year-old woman. By light microscopy, the tumor was composed of
Amarked increase in serum pancreatic lipase (PL) activity with minimal concurrent increase in serum alpha-amylase activity was observed in 6 dogs with pancreatic or hepatic neoplasia. Serum PL activity ranged from 5410 U/L to 42,900 U/L, 11 to 93 times the upper reference limit for our laboratory.
A rare intracerebral granular cell tumor (GCT) was studied by immunocytochemical and ultrastructural methods. The tumor was composed of two cell types--filament-rich and granular cells. Granular cells contained PAS-positive, diastase-resistant granules that ultrastructurally corresponded to
Loss of O-acetyl substituents from sialic acid expressed in mucin secreted by hyperplastic polyps (21), adenomas (9), a mixed polyp (1) and adenocarcinomas (41) of the colorectum was investigated by mucin histochemistry (diastase PAS and mild PAS) and by lectin histochemistry (Arachis hypogaea or
Hyaline globules (HGs), spherical intracytoplasmic eosinophilic droplets, have been associated with a variety of conditions, including hepatocellular carcinoma, lung adenocarcinoma, and Kaposi's sarcoma, but they have not been described in cartilaginous tumors. In specimens of 60 cartilaginous
A cell line derived from human endometrial clear cell adenocarcinoma was newly established and named TEN. The tumor cells were obtained from uterine body of a 74-year-old who had been undergone an abdominal simple hysterectomy. The histologic features of the tumor cells showed abundant clear
BACKGROUND
Clear cell carcinoma of the bladder is a rare variant of urinary bladder adenocarcinoma. We report a case of a patient with clear cell carcinoma of the bladder and a concordant right upper lobe pulmonary adenocarcinoma with clear cell features, and we address the role of
We report here a case of peripheral neuroepithelioma arising in the uterine cervix. A 44-year-old female had complained of irregular genital bleeding for several months and was diagnosed as extraosseous Ewing's sarcoma (EOE) from biopsy specimens initially. The tumor cells, which were intensely
Granular cell tumours (GCTs) are uncommon neoplasms mostly reported in man, dogs and horses. The origin of GCT is thought to be Schwann cells, with the associated characteristics of neural crest morphology. Neoplastic cells often demonstrate positive immunoreactivity for S100, LC3, vimentin and p62.
