Milia en plaque on the shoulder as an early manifestations of mycosis fungoides.

Milia en plaque (MEP) is an uncommon skin condition identified as retroauricular confluent milium by Boulzer and Fouqet in 1903 [1]. It can be mistaken for other dermatoses like Favre-Racouchot nodular elastosis, steatocystoma multiplex, and nevus comedonicus. Milia en plaque can either be primary or secondary and is typically benign, often triggered by dermatological procedures like cryotherapy, as reported in this journal. In some cases, MEP can arise as a secondary manifestation of other diseases, including folliculotropic mycosis fungoides (FMF). Despite this association, there are few documented cases in the literature. Herein, we present a patient in whom MEP served as the initial clinical presentation of FMF; the treatment involved oral retinoids and phototherapy. Furthermore, we highlight distinctive features of both conditions. It is important to emphasize that early diagnosis and treatment of FMF are vital for the patient's quality of life. The presence of MEP can serve as a valuable indicator for identifying it.

Primary cutaneous centrofollicular lymphoma with a good response to radiotherapy.

Primary cutaneous lymphomas have different clinical behavior and prognosis than systemic lymphomas of similar histological subtype. About 30% of non-Hodgkin lymphomas involve extranodal tissues, the skin being the second most affected body organ after the gastrointestinal tract (approximately 18%). According to the EORTC (European Organization for Research and Treatment of Cancer) classification, the lymphoma centrofollicular is indolent, since the lesions increase in size slowly over the years and spread to extracutaneous sites is uncommon. Based on this, radiotherapy has been considered the treatment of choice by many studies. We present the case of a patient who had cutaneous centrofollicular scalp lymphoma for 1 year and showed good response to radiotherapy.

Os linfomas cutâneos primários têm comportamento clínico e prognóstico diferente dos linfomas sistêmicos de subtipo histológico semelhante. Cerca de 30% dos linfomas não-Hodgkin acometem tecidos extranodais, sendo a pele o segundo órgão mais envolvido após o trato gastrointestinal (aproximadamente 18%). De acordo com a classificação EORTC (European Organization for Research and Treatment of Cancer), o linfoma centrofolicular cutâneo é indolente, uma vez que as lesões aumentam de tamanho lentamente ao longo dos anos e a disseminação para sitios extracutâneos é incomum. Com base nisso, a radioterapia tem sido apontada como o tratamento de primeira escolha por muitos estudos. Apresentamos um caso de paciente com linfoma cutâneo centrofolicular no couro cabeludo há 1 ano e que apresentou boa resposta à radioterapia.

Biopsy guided by dermoscopy in cutaneous pigmented lesion -- case report.

It may be clinically difficult to differentiate early-stage melanoma from benign tumors, specially pigmented seborrheic keratosis. Dermoscopy can help; however, the findings are not always conclusive. Therefore, histopathology may be necessary for a correct diagnosis. We describe a melanocytic lesion with dubious clinic and dermoscopic findings. An incisional biopsy of a suspicious area, guided by dermoscopy, was performed to clarify the findings.
