Mucinosis folicular. Reporte de caso

Abstract

This research explores follicular mucinosis, characterized by abnormal mucin deposition in hair follicles and sebaceous glands. It may correspond to a benign, self-limiting idiopathic disorder, especially in children, or represent a secondary condition to a myeloproliferative disorder, generally a cutaneous T-cell lymphoma. The aim of the study focused on presenting a clinical case study of a patient with follicular mucinosis. The methodology employed a qualitative, descriptive approach, utilizing a clinical case study method of a 19-year-old male patient who presented for consultation with a two-week history of hypochromic plaques with irregular borders and slight scaling on the skin of the back at the cervical and dorsal levels, extending to the lumbar region or lower back. Similarly, in the scalp, in the occipital region, alopecic plaques with slight scaling were observed, associated with a presumptive diagnosis of tinea corporis. It is concluded that follicular mucinosis is a skin condition with various clinical manifestations, such as defined skin lesions, erythematous plaques with follicular hyperkeratosis, and hair loss. Histopathological findings include mucin in hair follicles and Pautrier microabscesses. Treatment varies according to the patient, with topical tacrolimus, methylprednisolone acetate, clarithromycin, UVA-1 phototherapy, isotretinoin, and tazarotene being effective. It is crucial to personalize treatment based on the patient's response and clinical presentation.
