PatientID: DHPLC 1

KindredID: 1

Case: M, 51Y0M, Unknown Ethnicity

DiseaseAssertion: Assumed VHL

FamilyInfo: The patient’s daughter (DHPLC 1) had a pheochromocytoma at 11Y. At 18Y, she had a pheochromocytoma in the contralateral adrenal gland and two concurrent paragangliomas of the abdominal aorta and urinary bladder. At 25Y, she was found to have a right frontal meningioma. A family history obtained from his daughter’s other parent, one son and one other daughter (not DHPLC 1) was uninformative. The patient’s relatives (except for his daughter) were normal both clinically and biochemically.

CasePresentingHPOs: HP:0001028; HP:0000277; HP:0009715; HP:0000107 (Angioma, abnormality of the mandible, papillary cystadenoma of the epididymis, renal cyst)

CaseHPOFreeText: The patient had an attenuated VHL phenotype caused by mosaicism which led to what initially appeared to be a de novo mutation in his daughter (DHPLC 3). The patient was found to have an angioma of the glans penis and had had surgery for a mandibular cyst and epididymal cystadenomas at age 43Y. Abdominal ultrasonography and total-body magnetic resonance imaging (MRI) conducted at the time of the study (51Y) revealed a 2.3-cm cyst in his right kidney. His blood pressure and levels of plasma free metanephrines, fractionated urinary metanephrines, chromogranin A were normal.

VariantEvidence: Despite the identical bandshifting to her son, there were differences in the intensity of the aberrant bands (Fig.1a), suggested that the mother could be a somatic mosaic. To test this hypothesis the molecular analysis was repeated on tissues of different embryonic origin. DNA extracted from the mother's buccal mucosa showed higher levels of intensity of the same altered bands (Fig. 1b). The amplification products of exon 3 of the two mutated individuals were subjected to Fok I digestions that further confirmed the presence of mosaicism in the mother, as evidenced by the lower intensity of the fragments generated by the newly created restriction site (Fig.2).

CaseHPOFreeText: Previously undergone excision of cerebellar haemangioblastoma in 2003. He had also undergone bilateral nephron sparing surgery for ccRCC (stage pT1a, Fuhrman grade up to 3) in 2005 and renal radiofrequency ablation in both 2008 and 2012. CT imaging demonstrated an ethmoid mass measuring 35 × 34 × 44 mm. The patient underwent endoscopic transsphenoidal resection of the lesion in 2012. Two years later, in 2014, sinonasal tumour recurrence was suspected and imaging demonstrated limited progression in the nasal cavity. Excision biopsy was performed and appeared complete, with no evidence of residual tumour. Subsequently, symptoms recurred. Therapeutic excision was performed in 2015 and again in 2016. To date, the patient's VHL disease remains stable with no evidence of new lesions or metastatic disease.

CaseHPOFreeText: Patient presented with right sided neck mass that had been causing discomfort for two months. MRI showed a 9-mm rim-enhancing lesion in the right parotid that prompted consideration of malignancy. A parotidectomy revealed a well-demarcated 0.7-cm cyst filled with thick, white to translucent, mucoid material. Histologic examination demonstrated that the cystic tumor with an invasive but well-circumscribed border. The majority of the neoplasm was cystic, and there was no necrosis, appreciable mitotic activity, or cellular pleomorphism or anaplasia, indicative of a low-grade mucoepidermoid carcinoma. She previously had surgical excision of hemangioblastomas of the brain and spinal cord as well as resection of a pheochromocytoma of the left adrenal gland. Additionally, she also had been followed for 2 small pancreatic nodules that were subsequently found to be neuroendocrine tumors. The patient ended up requiring a partial pancreatectomy for a pancreatic neuroendocrine tumour related to her VHL disease.
