Contribution to characterization of skin field cancerization activity: morphometric, chromatin texture, proliferation, and apoptosis aspects,

An. bras. dermatol; 94 (6), 2019
Abstract Background: A skin field cancerization is a cutaneous area with subclinical changes resultant from chronic sun exposure, with a higher predisposition to development of pre-neoplastic and neoplastic lesions.

Actinic keratoses: review of clinical, dermoscopic, and therapeutic aspects

An. bras. dermatol; 94 (6), 2019
Abstract Actinic keratoses are dysplastic proliferations of keratinocytes with potential for malignant transformation. Clinically, actinic keratoses present as macules, papules, or hyperkeratotic plaques with an erythematous background that occur on photoexposed areas. At initial stages, they may be bett...

Melanoacanthoma: a potential pitfall of reflectance confocal microscopy

An. bras. dermatol; 94 (6), 2019
Abstract Melanoacanthoma is a rare variant of seborrheic keratosis, which is notable for dark pigmentation and fast radial growth, making it difficult to distinguish from melanoma. Histologically, it is characterized by proliferation of keratinocytes and dendritic melanocytes. The authors report a scalp ...

Primary scrotal melanoma: it is time to destigmatize genital lesions

An. bras. dermatol; 94 (6), 2019
Abstract Primary male genital melanomas are very rare; they are associated with high mortality and late detection. Scrotal melanoma is the least common presentation and only 23 cases have been reported. Herein, the authors present a 30-year-old patient with stage IIIC (T4b, N2a, M0) scrotal melanoma in o...

Horizontal histological sections in the preliminary evaluation of basal cell carcinoma submitted to Mohs micrographic surgery

An. bras. dermatol; 94 (6), 2019
Abstract Background: Mohs micrographic surgery is a surgical technique for the treatment of nonmelanoma skin cancer. Surgery begins by removing the visible tumor before excision of the tissue specimens for evaluation of the tumor margins. Objectives: To present a new way to evaluate the material obtain...

Use of methotrexate in an exuberant case of confluent and reticulated papillomatosis of Gougerot and Carteaud in a teenager

An. bras. dermatol; 94 (6), 2019
Abstract Confluent and reticulated papillomatosis of Gougerot and Carteaud is a rare dermatosis with onset during puberty, more prevalent in females than in males. The pathogenesis is unknown, but some theories suggest either a keratinization or endocrine disorder. The lesions are verrucous, brownish, hy...
