Unusual clinical case report, follicular Mucinosis

Abstract

Follicular mucinosis has been a rare skin disorder characterized by diffuse deposition of mucin in the skin, particularly in the pilosebaceous unit. The condition has been part of cutaneous mucinosis, a group of disorders characterized by an abnormal accumulation of mucin, a gelatinous substance found in the extracellular matrix of the skin. The cause of follicular mucinosis has not been completely established, which means that its origins have remained uncertain. However, it is recognized that it can present in two different clinical forms: primary (also called idiopathic) and secondary. Primary follicular mucinosis without a clear underlying cause occurs, tends to affect young adults, is usually self-limited, and has a favorable prognosis. Secondary forms, on the other hand, may be associated with benign conditions, such as seborrheic dermatitis, or with malignant conditions, including cutaneous T-cell lymphomas, especially mycosis fungoides. Among the clinical cases analyzed, a detailed report of follicular mucinopathy is provided, emphasizing the clinical characteristics of the patient, the differential diagnosis and the therapeutic management strategies implemented. This approach is essential to adequately address the disease, as treatments can vary greatly depending on the presentation and any underlying malignant or benign associations that may exist.
