RESUMO
We present the case of a 46 years old gentleman with longstanding ulcerative lesion of the right upper eyelid. Biopsy of the lesion revealed intracellular periodic acid–Schiff positive round to oval organisms with a surrounding clear halo suggestive of histoplasmosis. Histoplasma capsulatum specific polymerase chain reaction was positive. The patient was treated with oral antifungals and showed a prompt response to treatment. We report this rare case of primary cutaneous histoplasmosis of the eyelid in an otherwise healthy adult patient.
RESUMO
Eosinophilic angiocentric fi brosis is a rare condition presenting with tumefactive lesions of the nasal cavity, paranasal sinuses, upper respiratory tract and rarely the orbit; and has characteristic histopathological features. We report the case of a 38-year-old lady with a mass lesion in right orbit. Histopathological examination of the biopsy specimen revealed extensive areas of perivascular fi brosis showing a characteristic angiocentric whirling with onion skin pattern; along with perivascular exudates of eosinophils accompanied by collection of plasma cells and lymphocytes. Rheumatology review and autoimmune screening was negative. She underwent surgical debulking followed by tapering course of oral steroids and was completely free of orbital disease at her last follow-up visit.
RESUMO
Dermoid cysts are choristomas resulting from the inclusion of ectodermal tissue during closure of the neural tube and occur along the epithelial lines of fusion. Frontotemporal dermoids are the most common type and generally present as an asymptomatic mass. We present an unusual case of frontotemporal dermoid presenting as sudden onset oculomotor nerve palsy in young male patient and describe the neurosurgical approach in its management.
