A Rare Case of Carney-Stratakis Syndrome in a Patient With SDHA Mutation


Figure 1.
Figure 1. Endoscopy showed a 35-mm gastric sub-mucosal hemorrhaging lesion.
Figure 2.
Figure 2. Histologic features of the gastric GIST. (a) Low magnification showing a well-circumscribed tumor localized in the gastric wall and sparing the mucosa (left upper part of the image) (hematoxylin-eosin, × 20). (b) Higher magnification showing a relatively bland proliferation of oval cells with a moderate amount of cytoplasm. Mitoses were inconspicuous. (c, d) At immunohistochemistry, neoplastic cells were diffusely positive with DOG-1 (c) and CD117/Kit.

Figure 3. (a) Gastric neoplasm and a 10-mm intense (150 HU) nodule on the right adrenal gland at contrast CT scan of abdomen. (b) Intense uptake of the radiotracer at the level of gastric neoplasm and right adrenal gland at 18FDG-PET.
