A glomus tumor is a mesenchymal neoplasm that usually develops in the peripheral soft tissue, especially in the distal part of the extremities. The subungual zones of the fingers and toes are the most frequent sites of observation. The majority of glomus tumors are entirely benign, and the malignant counterparts are very rare, especially those arising in the visceral organs. We report a case of an extremely rare malignant glomus tumor arising in the stomach of a 53-year-old female admitted to the King Khalid University Hospital, Saudi Arabia. The patient reported a four-month history of pain and fullness in the left hypochondrium. She underwent laparotomy and resection of the gastric mass. The mass was analysed by histopathology. Based on the pathological findings of large tumor size, nuclear atypia, increased mitotic rate, atypical mitosis, the presence of necrosis, and characteristic immunohistochemistry the diagnosis of malignant glomus tumor was rendered. Ultrastructural study confirmed the diagnosis. The patient is well and continues regular follow-up.

The histopathological diagnosis of early MF lesions and their discrimination from inflammatory simulators can be achieved by carefully observing the hyperconvoluted dermal and epidermal lymphocytes along with the constellation of the other parameters.

Testicular hemangioma is a very rare benign vascular neoplasm, mostly occurring in children and young adults. We present a case of capillary hemangioma of the testis in a twenty three years old male who presented with painless mass in the right scrotum of 2 months duration. He was diagnosed with a right testicular tumor based on the physical examination, ultrasonography and magnetic resonance imaging studies. Serum tumor markers were normal. Right radical orchiectomy was performed. On histology, the tumor was diagnosed as capillary hemangioma of the testis. Immunohistochemical staining for CD31 and factor VIII confirmed the vascular nature of the tumor. To our knowledge, there are only twenty two cases of testicular hemangiomas reported in the literature. Although it is a rare tumor, surgeons and pathologists should be aware of it especially with the negative tumor marker findings. Intra-operative frozen section examination may be requested as tumor enucleation with testicular sparing surgery is considered adequate.
