Co-existence of BHD and other inherited conditions: new case report

Whitworth et al. (2016) present the case of a 58-year-old woman with a variety of disease manifestations including an oncocytoma in the submandibular gland, presence of multiple hemangiomas/cavernous malformations in the cerebrum and cerebellum, pulmonary bullae, a spontaneous pneumothorax episode, a goitre and facial rash.

From the medical history and clinical manifestations, two rare diseases were considered: BHD and hereditary cavernous cerebral malformations (CCM). Genetic testing of the relevant genes revealed mutations in the FLCN and CCM2 genes. Follow-up scan of the kidneys showed multiple small cysts and pulmonary bullae.

The authors suggest that when potentially novel clinical features are manifested, co-existing conditions should be considered and extensive genetic testing should be performed. The increased use of next generation sequencing in diagnosis is likely to reveal more cases such as this.
