These results show an increased risk of diabetes mellitus in patients with multiple skin tags. With regard to the importance of early diagnosis of diabetes, we recommend a high level of suspicion for impaired carbohydrate metabolism in patients with skin tag.

Macular amyloidosis is a relatively common cutaneous disease in Asia and the Middle East. It is characterized by a reticulated or rippled pattern of pigmentation mostly in the upper back. This study was performed not only to determine the disease sex and age distribution, but also to evaluate its risk factors and the frequency among the dermatology clinic patients. Based on the clinical and random histopathologic findings, 100 macular amyloidosis patients were evaluated in a period of 3 years. Although the sex distribution (9 : 1, female : male ratio) differed dramatically from most of the previous reports, it was consistent with few other series. Eighty one percent of patients were between 21 and 50 years of age. The mean age of the female patients was higher than that of the males (difference of two means was 10.26 years and P = 0.027). Backscatching during bathing probably is not a common practice in Iran, therefore we could not consider this as a risk factor in our study. We found no evidence of any other associated risk factors.

Becker's nevus is a relatively common cutaneous hamartoma, but is often overlooked or misdiagnosed. This nevus usually begins during the second decade of life as a circumscribed, hyperpigmented patch with irregular outline that gradually enlarges with associated hypertrichosis, developing several years later. The purpose of this study was to determine the prevalence of lesional hypertrichosis associated with Becker's nevus. Methods. 47 patients who had sharply demarcated brown patch with or without coarse hair, presence or enlargement of the lesion at the time of puberty, and compatible Wood's light examination were enrolled. Patients who had axillary freckling, previous skin inflammation, and gray pigmentation of the lesions were excluded. Results. In summary, the mean age of onset was 11.89 (range 0–19). The most commonly involved site was the arm (34%), followed by shoulder (23.4%), chest, face, flank, buttock, and leg. Lesional hypertrichosis was found in only 8 (17%) of the 47 patients. In 29 cases (61.7%) the lesions were in the right side of the body. Conclusion. Hypertrichosis was not so frequent among patients with Becker's nevus. There was a higher preponderance of the lesions on the right side.

Autoimmune progesterone dermatitis is a rare cutaneous disorder characterized by recurrent cyclic eruptions with variable morphology occurring during the luteal phase of the menstrual cycle. We report a case of a 40-year-old woman with recurrent pruritic eruptions of 8 years' duration. The possibility of autoimmune progresterone dermatitis was raised because of the cyclic nature of the exacerbations. We used oral estrogen both to confirm the diagnosis and to treat the patient. A brief review of the clinical features of the disease is also presented.
