A rare case of hereditary spastic paraplegia: Case report.

Hereditary spastic paraplegias represent a rare set of monogenic disorders encompassing 79 distinct genetic variations. The principal culprit behind recessive hereditary spastic paraplegia is frequently attributed to mutations in the spastic paraplegia gene, particularly type 11, closely followed by type 15. This category is typically characterized by nonspecific clinical features, including cognitive decline, which may precede the development of progressive lower limb weakness and spasticity.

A Case of Well-Differentiated Papillary Mesothelioma of the Male Peritoneum: Successful Treatment by Systemic Chemotherapy.

The patient, who had no history of asbestos exposure, presented with abdominal pain and ascites of unknown etiology.
