TLDR Accurate diagnosis of pseudolymphomatous folliculitis is crucial to avoid mistaking it for more serious conditions.
The document discussed a case of pseudolymphomatous folliculitis (PLF) in a 19-year-old male with a solitary violet erythematous nodule on the right infraorbital region. Histopathological and immunohistochemical studies confirmed PLF, characterized by a dense lymphocytic infiltrate surrounding hair follicles and glands. The patient had no recurrence over 4 years of follow-up. PLF is a rare, benign cutaneous lymphoid hyperplasia that mimics other conditions, requiring detailed histological analysis for accurate diagnosis. The case highlighted the importance of differential diagnosis, including conditions like follicular mycosis fungoides and granulomatous rosacea, to ensure appropriate treatment.
