“…In our previous work, we have revealed that progression or relapse tended to be more frequent in patients with extra copies of MALT1 [30]. Conversely, MALT lymphoma with increased plasma cell differentiation shows favourable treatment response [31, 32]. Based on the outcome observed in Case 2 of the present report, careful follow-up may be necessary in patients with gastric MALT lymphoma resembling follicular gastritis to detect relapse.…”

In this report, we describe two cases of extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) of the stomach, which presented with multiple small, whitish nodules in the gastric body. The endoscopic appearance was similar to that of lymphoid follicular hyperplasia found in follicular gastritis or nodular gastritis. Both patients were positive for Helicobacter pylori , and the eradication treatment resulted in complete remission of the lymphoma. However, recurrence was noted in one patient. These cases indicate that, although infrequent, gastric MALT lymphoma can show a nodular appearance resembling that of follicular gastritis.

Primary epithelioid rhabdomyosarcoma of the stomach: a case report and review of literature

BackgroundEpithelioid rhabdomyosarcoma is a rare tumor that generally occurs in the bladder, the parotid gland, or the skin of the neck. We describe an unusual case of primary epithelioid rhabdomyosarcoma of the stomach and review the literature.Case presentationA 64-year-old woman presented with a lesion at the gastroesophageal junction. Histopathological examination showed irregularly sized round cells with low cytoplasmic content and eccentric nuclei. Mitotic figures were present. Fibrovascular septa and areas of necrosis were observed between tumor cells. Tumor cells were strongly positive for MyoD1, desmin, and myogenin, and weakly positive for actin, CD56, and PGP9.5. The ki-67 index was ≥90%.ConclusionsPrimary epithelioid rhabdomyosarcoma of the stomach is extremely rare. Better awareness of this entity is necessary for early diagnosis and treatment.

“…Myeloid sarcoma in the stomach is a localized tumor formed by extramedullary proliferation and infiltration of myeloid primordial cells or immature myeloid cells. These tumors are positive for MPO, lysozyme, CD68, and CD117, but negative for CD3, MyoD1, myogenin, and myoglobin [17][18][19][20][21][22][23].…”

A case report of primary intraabdominal rhabdomyosarcoma presenting as metastasis

et al. 2023

Rhabdomyosarcoma (RMS) is a rare and in adult accounts for only 1-3% of all malignant soft tissue tumors. The most frequent sites of origin is within head and neck area. One of the least common sites is the retrorectal-presacral space. This case of 61 years old female is probably the fifth well-documented case of primary abdominopelvic RMS. She presented with abdominal distensions, obstipation, vomiting for 5 days. Excision of the gut wall along with soft tissue mass was done and sent to our department for histopathological examination. On microscopic examination, a diagnosis of malignant mesenchymal tumor with closest resemblance to RMS was made. It is a rare case and needs to bring in notice as there is very few information regarding intraabdominal RMS. This case initially thought to be metastasis from gynecologic malignancy. It is important for pathologists, gynecologists and radiologists to recognize RMS as differential diagnosis of masses arising in abdomen and pelvis.
