First report of rare persistence granulomatous extra respiratory Rhinoscleroma of oral pathology.

Rhinoscleroma (RS) is a rare chronic specific progressive granulomatous disease of the upper airway and affect the nasal cavity, larynx, nasopharynx and may spread to the lower respiratory tract. Extra-respiratory involvement has rarely been described. A case report of extra-respiratory RS with oral manifestation in Egyptian female patient has been presented as a tumour extruded from mucosal lining of upper lip. She was living in crowded conditions with malnutrition and poor hygiene. On the first look, the lesion appeared to be carcinoma without any indication of infectious disease, and then patient was prepared for incisional biopsy. Upon clinicopathological evaluation, the diagnosis was made as RS in the granulomatous stage based on the presence of dense plasma cell infiltration with Mikulicz cells and Russell bodies. Long term oral ciprofloxacin 500 mg twice/day was started as a single treatment. By the end of six weeks antibiotic therapy, the large granulomatous mass reached the cicatricial stage, became very stiff fibrotic mass with sclerotic scar, markedly indurated & significantly decreased in size. This case shows the significant of through clinical examination and lab investigations to achieve correct diagnosis.
