Mucormycosis is an uncommon opportunistic fungal infection mostly affecting immunocompromised patients and gastrointestinal mucormycosis is a rare and life-threatening. We describe a 31-year-old man with a history of idiopathic cyclic neutropenia who developed perforations of the stomach and intestine and intra-abdominal bleeding due to disseminated gastrointestinal mucormycosis after the initial operation.

Thirty two cases of nevus sebaceus were studied by immunohistochemical staining employing three anticytokeratin antibodies(34bE, 34bB, CAM 5.2) and anti-involucrin antibody in order to clarify the biochemical characteristics of the covering epidermis of nevus sebaceus. An attempt was made to compare the expression pattern of these proteins in the epidermis of nevus sebaceus with that in normal skin and in epidermal nevus. Serial sections in all cases were also stained with PAS in attempt to correlate these protein expression with the amount of glycogen in the epidermis of nevus sebaceus. The following results are obtained. 1. The expression of cytokeratin and involucrin in the epidermis of nevus sebaceus was changed as the age of the lesions increased, but we could not identify a uniform pattern according to the age of lesions. 2. Several CAM 5.2 positive cells were found in the basal layer of the epidermis of nevus sebaceus lesion obtained from patients over 10 years of age. 3. The expression of cytokeratin and involucrin did not show any correlation with glycogen content. These results suggest that the covering epidermis of the lesion of nevus sebaceus may not be nevoid proliferation of epidermal nevus.

BACKGROUND: In the course of the study of keratin expression in the epidermis of nevus sebaceus, several cells in the epidermis of nevus sebaceus were positively stained with CAM 5.2 antibody, which is known to be specific for the lower molecular weight cytokeratin and used as a marker of Merkel cell. OBJECTIVE: This study was intended to verify that CAM 5.2 positive cells found in the epidermis of nevus sebaceus are Merkel cells and to understand the meaning of CAM 5.2 positive j cells in the epidermis of nevus sebaceus. METHODS: The immunohistochemical stainings with CAM 5.2 and antibody to epithelial membrane antigen (EMA) performed on specimens of normal skin, epidermal nevus, nevus sebaceus and some appendage tumors. In order to confirm the nature of CAM 5.2 positive cells, the distribution of those were compared to that of Merkel cells and double labeling with CAM 5.2 and neurofilament was performed. RESULTS: CAM 5.2 positive cells were also found in trichilemmoma developed associated with nevus sebaceus and the epidermis of normal paimoplantar skin. CAM 5.2 positive cells were also stained with antibody to EMA on serial sections cut from the same tissue blocks. The association of CAM 5.2 positive cell and nerve fiber was also demonstrated. CONCLUSION: CAM 5.2 positive cells are seemed to be Merkel cells and their presence in the covering epidermis of nevus sebaceus suggests to the epidermis of nevus sebaceus may not be nevoid proliferation of epidermal keratinocytes.
