Milium cysts on hands; hypertrichosis on face.

The patient's dermatologic symptoms and his history of a particular chronic condition pointed toward the diagnosis.

Dermoscopy of skin infestations and infections (entomodermoscopy) - Part I: dermatozoonoses and bacterial infections.

Dermoscopy is an essential in vivo diagnostic technique in the clinical evaluation of skin tumors. Currently, the same can also be said about its implications when approaching different clinical situations in Dermatology. A growing number of reports on dermatological scenarios and diseases have been published, in which dermoscopy has been of great diagnostic help.

Xanthoma striatum palmare and biliary tract atresia: An unusual association.

Cutaneous xanthomas develop as a result of lipid deposition in the dermis and may be a manifestation of various systemic diseases. The morphology and anatomic location of xanthomas are often a clue to the underlying cause. Xanthoma striatum palmare (XSP) is classically associated with dysbetalipoproteinemia and rarely observed in hepatic disorders.

Eruptive Xanthomas: A Dermatologic Clue to the Diagnosis of an Underlying Metabolic Disorder.

A 32-year-old man presented to the dermatology department with generalized asymptomatic yellowish papules on an erythematous base, arms, thighs, and buttocks. These lesions had appeared in the previous month (Figure 1). Dermoscopy revealed a homogeneous yellow color, corresponding to dermal xanthomatous deposits, with interconnected fine and dotted vessels (Figure 2).

Dermoscopy of Dermatofibrosarcoma Protuberans: What Do We Know?

Background: Dermatofibrosarcoma protuberans (DFSP) is an uncommon mesenchymal tumor of intermediate malignancy. Its rarity and slow progression often imply a delayed diagnosis. There are few previous reports of dermoscopic features of DFSP and most are single case descriptions.

Syndrome in Question.

Waardenburg syndrome is an inherited disease characterized by sensorineural hearing loss, pigmentation changes and minor facial malformations. It has four clinical variants. We report the case of a girl who, like her mother, was affected by this syndrome.

Syndrome in question. A case of Cowden´s syndrome.

The authors describe a case of Cowden's syndrome in a female patient with classic cutaneous lesions, plus papillomatous lesions in the gastrointestinal tract and a previous history of thyroid carcinoma. Mucocutaneous lesions occur in 90% of Cowden's syndrome cases and are characterized by facial trichilemmomas, oral mucosal papillomas and benign acral keratoses. Sites of extracutaneous involvement include: the thyroid, gastrointestinal tract, breast and endometrial tissue.

Translation into Brazilian Portuguese and validation of the "Quantitative Global Scarring Grading System for Post-acne Scarring".

The "Quantitative Global Scarring Grading System for Postacne Scarring" was developed in English for acne scar grading, based on the number and severity of each type of scar. The aims of this study were to translate this scale into Brazilian Portuguese and verify its reliability and validity. The study followed five steps: Translation, Expert Panel, Back Translation, Approval of authors and Validation.

Livedoid vasculopathy associated with peripheral neuropathy: a report of two cases.

Livedoid vasculopathy (LV) is a chronic and recurrent disease consisting of livedo reticularis and symmetric ulcerations, primarily located on the lower extremities, which heal slowly and leave an atrophic white scar ("atrophie blanche"). Neurological involvment is rare and presumed to be secondary to the ischemia from vascular thrombosis of the vasa nervorum. Laboratory evaluation is needed to exclude secondary causes such as hyper-coagulable states, autoimmune disorders and neoplasms.
