RESUMO
Dactylitis due to tuberculosis (TB) is an extremely uncommon manifestation of TB. We report a unique case of isolated index finger dactylitis with right hilar adenopathy due to TB in a 15-year-old immunocompetent student. High index of clinical suspicion, radiological findings and histological confirmation helped in the diagnosis. Anti-tuberculous therapy remains the cornerstone for the management of these cases.
RESUMO
Pachydermodactyly (PDD) is a rare, benign form of digital fibromatosis that is characterized by asymptomatic soft tissue swellings on the back and side of the proximal interphalangeal joint areas of the fingers. We report three cases of young male patients who presented with bilateral swelling of the fingers. Histopathologic examination showed epidermal hyperplasia with acanthosis and hyperkeratosis. Collagen fibers in the reticular dermis were thickened and irregularly arranged, and deposition of mucin in the dermis was observed. Since pachydermodactyly usually affects adolescent males with joint swelling, it is often confused with rheumatologic diseases. Here, we report three cases diagnosed with pachydermodactyly based on clinical manifestations and histopathological examination.
