The Highly Active Antiretroviral Therapy promoted a better quality of life for seropositive patients. However, metabolic changes in patients, such as HIV lipodystrophy syndrome, may occur with antiretroviral therapy. Thus, it is necessary to adopt strategies to prevent and treat lipodystrophy and other possible side effects of. We report the case of a female patient with prior antiretroviral therapy and decreased thickness of the lower limbs bilaterally, especially in knees and distal third of the legs. The sites with evidence of lipoatrophy were filled with polymethylmethacrylate, with satisfactory results and adherence by the patient.

O queratoacantoma (QA), apesar de frequente na prática diária, é um tumor que gera questionamentos. O aspecto mais intrigante associa-se à sua posição no limite entre malignidade e benignidade. A abordagem do tumor, bem como sua classificação, é controversa. Na definição da conduta, é importante levar em conta o potencial de transformação para carcinoma espinocelular. Desse modo, a excisão cirúrgica é a terapia de escolha, sempre que possível. Algumas situações merecem atenção adicional, como a imunossupressão associada. Neste artigo, relatamos um caso de QA gigante em um paciente com síndrome da imunodeficiência adquirida tratado com cirurgia micrográfica de Mohs.

Eruptive vellus hair cyst is a rare and benign dermatological condition in the development of vellus-type hair follicles. It affects mainly children and young adults, and is characterized by multiple asymptomatic papules, especially on the trunk. We report the case of a 33-year-old white man who presented multiple erythematous papules and pustules located on the trunk for about five years, refractory to topical treatments for acne. Dermoscopy revealed oval lesions with eccentric exulceration and rare protruding filiform structures. We established the diagnosis of eruptive vellus hair cyst based on the findings of dermoscopy and histopathological examination.
