PAON responded with tazaroten gel, dithranol short-contact treatment and topical photodynamic therapy but laser treatments appear to be more efficient in most patients.
NICF is both a distinct entity and an epiphenomenon in the context of other disorders. In regard to the common association with yeasts and gram-positive bacteria in the affected follicles, we hypothesize that NICF is pathogenetically linked to these organisms, which is supported by resolution of the lesions after topical or systemic antimycotic treatment.
Mycosis fungoides is a cutaneous T-cell lymphoma (CTCL) usually observed in mid to late adulthood. It occurs only rarely during childhood. Follicular mucinosis is a chronic dermatosis involving the sebaceous glands and outer root sheaths. It is normally differentiated into a juvenile benign form and an adult form possibly associated with mycosis fungoides. We report a 12-year-old boy who presented with an 8-month history of erythematous mucinous plaques on the scalp. Three months later, he developed erythematous patches and plaques on his whole body, accompanied by cervical lymphadenopathy. A biopsy showed follicular mucinosis and epidermotropism of the lymphocytic infiltrate. Immunophenotyping and a PCR clonality test were consistent with CTCL. The patient received PUVA treatment and local steroids, resulting in partial remission. Mycosis fungoides should be considered in the differential diagnosis of chronic, scaling dermatoses in childhood. Moreover, follicular mucinosis in childhood can be associated with mycosis fungoides.
PDT is a safe, efficient and non-invasive therapeutical approach for the treatment of UMF and PR. It has no long-standing adverse events and therefore is of high therapeutic value especially in cases of UMF and PR located at special sites like the palms and soles. We propose to include topical PDT as therapeutic option for the treatment of UMF and PR in future guidelines on the management MF.
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.
