PIK3CA基因激活突变所导致的一系列发育障碍表型谱被统称为PIK3CA基因相关过度生长综合征群(PIK3CA-related overgrowth spectrum,PROS)。临床表现分型众多,各型分类见表1A。由于基因变异发生在受精卵形成后,临床表型为嵌合体,因此PIK3CA基因变异在外周血中的阳性检出率很低,通常需要非血液标本或通过组织活检来发现超低频嵌合体。PIK3CA基因激活变异的作用为促生长,变异导致的表型取决于基因变异发生的时间、组织细胞类型、变异细胞的分布以及变异的激活强度。 展开更多

Pheochromocytoma and ganglioneuroma form rare composite tumours of the adrenal medulla comprising less than 3% of all sympathoadrenal tumours. We present a case of intraoperatively detected adrenal medullary tumour of composite pheochromocytoma and ganglioneuroma diagnosed on histopathology, in a normotensive patient. A 50-year-old male with a past history of chronic obstructive pulmonary disease presented with abdominal pain and significant weight loss since one month. Ultrasound and contrast-enhanced computed tomography abdomen revealed a large lobulated lesion in the distal body and tail of pancreas suggestive of solid and papillary neoplasm of body and tail of pancreas. Intra-operatively, a 15 cm × 10 cm solid lesion with cystic areas was seen arising from the left lower pole of the adrenal gland pushing the pancreas which appeared unremarkable. In our case, exploratory laparotomy with tumour excision was done. Extensive sectioning and microscopic examination of this adrenal tumour confirmed a diagnosis of composite Pheochromocytoma with Ganglioneuroma on histopathology. Immunophenotyping with S-100 further supported the diagnosis. The goal of this report is to increase the awareness of this rare disease and to further identify its variable presentation. 展开更多
