Syringocystadenoma papilliferum (SCAP) and tubular apocrine adenoma (TAA) are rare benign sweat gland tumors. SCAP and TAA may have a histopathologic overlap, but few cases of a SCAP combined with a TAA have been reported. Herein we describe an unusual case of a SCAP co-existing with a TAA located on the back of a 12-year-old girl.

Hidradenitis suppurativa is a chronic, recurrent, debilitating disease that presents with inflamed lesions in the apocrine glands of the body. The most common locations are the axillary, inguinal and anogenital areas. Hidradenitis suppurativa is caused primarily by follicular occlusion with secondary involvement of the apocrine glands. The authors report a case of 47-old-man with an 18-year his...

Minute lesions of intestinal metaplasia composed of a few metaplastic tubules were observed in the gastric mucosa during routine histological examination of gastrectomy specimens. The histological findings indicated that these lesions might be an initial stage of more advanced intestinal metaplasia. Accordingly, more than 18,000 serial sections in 10 stomachs with chronic ulcers were examined t...

Intestinal metaplasia is a well-established premalignant condition of the stomach that is characterized by mucin carbohydrate modifications defined by histochemical methods. The purpose of the present study was to see whether the expression of mucin core proteins was modified in the different types of intestinal metaplasia and to evaluate the putative usefulness of mucins as "molecular markers"...

We determined the incidence of gastric metaplasia in the duodenal bulb of duodenal ulcer patients and the Helicobacter pylori (H. pylori) infection rate at sites with gastric metaplasia. Biopsy of the duodenal bulb showed the presence of gastric metaplasia in 61 of 86 patients (71%) overall and in 18 of 47 patients (38.3%) who had gastrectomy at an early gastric cancer. The histological diagnos...

Cutaneous apocrine carcinoma (AC) is a rare adnexal neoplasm that histologically can mimic breast carcinoma metastatic to the skin or apocrine carcinoma arising in ectopic breast tissue. As extremely rare condition, neuroendocrine differentiation may be observed in AC although its etiology and pathogenesis is still unclear. We report here a case of unusual AC with neuroendocrine differentiation...

A joint prospective long term study of gastric biopsies has been undertaken to survey intestinal metaplasia Types I, II, and III in terms of their incidence, distribution and value in the selection of high risk cancer patients. This study is based on protocols agreed between three centres for endoscopy, histological interpretation, and mucin histochemistry. The results on the first 1350 gastric...

Barrett's metaplasia consists of columnar epithelium that replaces the normal esophageal mucosa in patients with chronic gastroesophageal reflux. Because intestinal-type Barrett's metaplasia is the major risk factor for adenocarcinoma development, understanding the mechanisms that predispose the esophageal mucosa to malignant degeneration is clinically important. Glutathione s-transferase (GST)...

BACKGROUND The biological processes involved in the development of gastric mucosal atrophy and intestinal metaplasia are still incompletely understood. Reports testing the hypothesis that apoptosis leads to atrophy have yielded conflicting results. The availability of new antibodies for the detection of apoptotic cells in tissue sections has facilitated the analysis of the role of apoptosis in ...
