Resumen:
Pseudolymphomatous folliculitis is a rare entity included among the
cutaneous pseudolymphomas. A 32-year-old man, with an unremarkable
medical history, presented with a two-month history of an asymptomatic
solitary nodule on his left cheek. Histopathological examination
demonstrated a dense nodular and diffuse dermal lymphocytic infiltrate
with numerous histiocytes and dendritic cells that surrounded
hypertrophic hair follicles. Pseudolymphomatous folliculitis commonly
presents in the fourth decade of life, with no sex predominance, as an
asymptomatic, rapidly growing and solitary red dome-shaped nodule on the
face. It has a benign clinical course as the lesions usually resolve
with surgical excision or regress spontaneously after incisional biopsy.
Although there is no report of pseudolymphomatous folliculitis
progressing into lymphoma in the literature, follow-up of these patients
is recommended.
