Cicatricial alopecia (CA) encompasses a heterogeneous group of conditions characterized by the permanent destruction of hair follicles (HF), and irreversible hair loss. CA is classified in primary cicatricial alopecia (PCA) and secondary cicatricial alopecia (SCA). PCA includes multiple inflammatory diseases that primarily affect and destroy the HF. SCA is the follicular destruction caused by infections, neoplastic conditions, burns, or trauma. 1 Although SCA is a benign condition, permanent hair loss can be devastating to the patient's self-esteem. 2 Hair restoration surgery (HRS) has been used as an option for androgenetic alopecia (AGA) and stable PCA with favorable outcomes. 3,4 However, little is known about HRS for SCA, especially to affected areas other than the scalp. This paper presents three uncommon successful cases of SCA treated with HRS.A 35-year-old Caucasian man presented with SCA on the left eyebrow after a pressure injury due to prolonged hospitalization in the prone position. Follicular unit excision (FUE) was performed to harvest follicular units (FU) from the left parietal area. A total of 120 FU of one and two hairs were implanted on the eyebrow, using a 0.65 mm
A pitiríase rubra pilar (PRP) é uma doença crônica, papuloescamosa, de etiologia desconhecida. Embora existam casos familiares, a maioria é adquirida. Afeta homens e mulheres na mesma proporção, apresentando incidência bimodal com picos na primeira e quinta décadas de vida. Relatamos um caso clínico de pitiríase rubra pilar na forma clássica do adulto, em um paciente do sexo masculino, 40 anos de idade, que apresentava pápulas eritemato descamativas foliculares crónicas, de quatro anos de evolução, no dorso dos quirodáctilos. Neste estudo aborda-se a evolução clínica da doença, diagnósticos diferenciais, achados histopatológicos e o tratamento com acitretina.
RESUMOO angiossarcoma é uma rara neoplasia vascular originada das células endoteliais. É muito agressivo com alta taxa de recorrência, metástases precoces e mau prognóstico. O diagnóstico precoce do angiossarcoma é um desafio, pois muitas vezes apresenta-se como uma equimose ou pápula violácea que pode ser confundida com lesão benigna como um hemangioma. O tamanho do tumor é um fator prognóstico importante e o diagnóstico precoce e tratamento combinado são fundamentais para aumentar a sobrevida desses pacientes. Esse estudo relata o caso de um homem de 58 anos de idade com angiossarcoma de couro cabeludo altamente agressivo e prognóstico reservado.Palavras-chave: Angiossarcoma. Neoplasias.

ABSTRACTAngiosarcoma of the head and neck is a rare vascular sarcoma associated with high rates of local recurrence and distant metastasis and a poor prognosis. The diagnosis of cutaneous angiosarcoma can be challenging because it often presents insidiously as a bruiselike lesion or a purplish papule thatmay be mistaken for a benign lesion such as hemangioma. The tumor size is a important prognostic factor and a multimodality treatment approach is imperative for successful outcomes. This study reports the case of 58-years-man with angiosarcoma of the scalp aggressive and a poor prognosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
