Hepatocellular carcinoma presenting as an isolated sphenoid sinus lesion: a case report.

We report a rare case of a metastatic sphenoid sinus lesion originating from an undiagnosed hepatocellular carcinoma (HCC) in a 53-year-old man who presented with gradually progressive external ophthalmoplegia. Imaging showed a right sphenoid sinus lesion infiltrating the parasellar region. Although a primary sphenoid biopsy was inconclusive, positive hepatitis B surface antigen and CT-guided fine-needle aspiration cytology suggested an HCC.

A case of isolated laryngeal candidiasis mimicking laryngeal carcinoma in an immunocompetent individual.

Respiratory fungal infections are usually found in immunocompromised individuals who have received either long-term steroid therapy or broad-spectrum anti-microbial therapy or have a non-resolving underlying chronic disease. These infections are seen as a part of bronchopulmonary fungal infections, and their isolated and primary occurrence as laryngeal diseases is highly uncommon. Laryngeal fungal infections can also mimic various diseases, such as gastroesophageal reflux disease, granulomatous diseases, leukoplakia, and carcinoma, thereby misleading the treating team from correct diagnosis and management.
