Rare presentation of the glomus tumor in the stomach

Unusual glomus tumor of the bladder: a rare case report and literature review

Background

Glomus tumor (GT), which are neoplasms of the glomus body, usually occur in the extremities, particularly under the nail bed. GT occurring in the bladder is very rare and has been reported as sporadic. In the present study, a rare case of bladder GT is reported and its clinical and histopathological characteristics are summarized by literature review.

Case presentation

A 57-year-old woman presented with intermittent gross hematuria for 2 years. Urinalysis displayed hematuria. The bladder ultrasound showed an avascular and homogeneous isoechoic polypoid mass with a maximum diameter of 6 mm at the right lateral wall of bladder. The bladder endoscopic examination showed a polypoid lesion, with a smooth surface, located in the right lateral wall. Then, a transurethral resection was performed, its histopathological features indicated a benign GT.

Conclusions

GT arising in the bladder is extremely rare, and only four cases have been identified in studies reported in English. It is difficult to diagnose bladder GTs according to their clinical features. The gold standard method used for their diagnosis is histopathology. However, it should also be considered in the differential diagnosis for bladder mass.

Lesser Sac Glomangiosarcoma With Simultaneous Liver And Lymph Nodes Metastases Mimicking Small Bowel Gastrointestinal Stromal Tumor; Immunohistochemistry And Empirical Chemotherapy

Glomangiosarcoma is a rare malignant mesenchymal tumor. Despite malignant histopathological feature of glomangiosarcoma, metastasis was observed extremely rare in these tumors. Moreover, malignant glomus tumor with stomach origination and simultaneous metastasis to liver and lymph nodes were not reported so far. This report presented a 57-year-old male patient with an exophytic gastric glomangiosarcoma in lesser sac and simultaneous liver and lymph node metastasis.

Glomus tumor of the stomach: A case report

RATIONALE

Glomus tumors (GTs) are a rare disorder originating from the glomus of the anastomoses of small arteries, usually occurring in the subungual region of the fingertips or toes and seldom occurring in the stomach. We unintentionally found a case of a gastric glomus tumor (GGT) without any upper abdominal discomfort. The diagnosis of this disease was mainly by immunohistochemistry.

PATIENT CONCERNS

The patient presented to our hospital with intermittent right abdominal pain for 1 month. Abdominal computed tomography showed a nodular enhancement lesion in the gastric antrum.

DIAGNOSES

The patient was diagnosed with an ileocecal tumor and a gastric stromal tumor.

INTERVENTIONS

Surgical resection of the ileocecal and gastric tumors was performed.

OUTCOMES

Pathologic examination of gastric masses revealed GT. The operation was effective, and the patient was discharged from our hospital 7 days after surgery. Upon follow-up at 3 months, the patient was asymptomatic.

LESSONS

GTs are submucosal tumors rarely found in the stomach. Surgical resection is a good choice of treatment. The GGT lacked specific clinical and imaging features, and immunohistochemistry was essential in the diagnosis of GGT.
