ABSTRACT
Perinevic dermatosis neglecta is an underestimated skin condition usually affecting children and adolescents, characterized by the appearance of dirt-like brownish pigmentation around a preexisting nevus and often a matter of concern for parents. We describe the clinical and dermoscopic findings in a case of perinaevic dermatosis neglecta and discuss the possible etiology of this phenomenon.

Abstract Pruritic folliculitis of pregnancy is a rare disease of unknown etiology. It occcurs primarily during pregnancy, usually with spontaneous resolution postpartum. It is characterized by a benign dermatosis, with papular and pustular follicular lesions that first appear on the torso and occasionally spread throughout the body. We report the case of a patient in the 27th week of pregnancy, with a two-month evolution of pruritic and papular erythematous lesions on her lower back. Differential diagnosis includes other pregnancy-specific dermatoses: gestational pemphigoid, pruritic urticarial papules and plaques of pregnancy (PUPPP), prurigo of pregnancy, and (PUPPP) and prurigo of pregancy. Histopathological tests showed changes consistent with pruritic folliculitis of pregnancy. This case is relevant due to its rare nature and its clinical and histopathological characteristics.

Alopecia areata (AA) is a common form of autoimmune nonscarring hair loss of scalp and/or body. Atypical hair regrowth in AA is considered a rare phenomenon. It includes atypical pattern of hair growth (sudden graying, perinevoid alopecia, Renbok phenomenon, castling phenomenon, and concentric or targetoid regrowth) and atypical dark color hair regrowth. We report a case of AA that resulted in a concentric targetoid hair regrowth and discuss the possible related theories regarding the significance of this phenomenon.

BACKGROUND: Hyperhidrosis is a little known disorder, characterized by excessive production of sweat. Hyperhidrosis may occur under several circumstances and appears in body parts like armpits, hands, feet, and face, consequently causing problems to the patient like job limitation, social embarrassment, and psychological damage. OBJECTIVES: Using these theoretical views as a starting point, the study aimed to evaluate the prevalence of hyperhidrosis in Blumenau. METHODOLOGY: Utilizing interviews, the research was conducted with 500 subjects randomly approached, in the period ranging from August 21 to September 1st, 2006. RESULTS: 45 respondents (9%) matched the pre-requisites, being classified as hyperhidrosis patients. The age group most affected was from 18 to 30 years (11.8%). Hyperhidrosis was more frequent among men both in absolute (24 men against 21 women) and relative numbers (10.62% of men against 7.66% of women). The most prevalent characteristic was 'at least one occurrence per week', in 91.11% of patients; the least prevalent occurrence was 'cessation of sweat during sleep', in 37.77% of respondents. CONCLUSIONS: The data show that the prevalence of hyperhidrosis in Blumenau is higher when compared with other studies, thus indicating that it is not a rare phenomenon.
