A 30-year-old man came with complaints of generalized body pain, fatigability, dyspepsia, anorexia, weight loss, and exertional breathlessness for 6 months with no history of chronic illness, addiction or blood loss from any site in body. His vitals were stable. The conjunctiva was pale. Lymph nodes were not enlarged. Hemogram showed bicytopenia with hemoglobin of 4.2 g/dL, leukocytes 15,500/mm3 and platelets of 62,000/mm3. The peripheral blood film showed leukoerythroblastic picture. The bone marrow biopsy revealed infiltration with malignant cells [Figure [Figure1a,1a, and andb].b]. Gastroscopy showed an ulcerated hypertrophic mass lesion along the greater curvature of the stomach (3 cm × 3 cm). Histology of the gastric tissue showed poorly differentiated adenocarcinoma of the stomach, which stained positive for pan-cytokeratin applied with immunohistochemistry [Figure [Figure1c1c and andd].d]. The liver was normal on contrast enhanced computerized tomography. The serum alkaline phosphatase (ALP) value was 220 IU/L, serum lactate dehydrogenase (LDH), 250 IU/L, and serum calcium was 9.2 mg/dL. The liver and renal function tests, serum carcinoembryonic antigen, carbohydrate antigen-19-9, and coagulation profile was within normal limit. He tested negative for HIV, hepatitis B virus, hepatitis C virus, and coombs test. The chest X-ray, electrocardiogram, colonoscopy, digital X-ray of spine and echocardiogram were normal. He expired after 50 days of admission on supportive treatment in the form of blood product transfusion.

The solid malignancies which commonly metastasise to bone marrow are breast, prostate, and rarely gastric cancer. The patients with bone marrow metastasis of gastric cancer are often younger and present with refractory anemia, cytopenias, elevated ALP, LDH, osteolytic lesions, and lower incidence of hypercalcemia with poorly differentiated adenocarcinoma being most common type. To conclude, case presenting with leukoerythroblastic picture on peripheral blood film, should be evaluated for the infiltrative pathology of the bone marrow. Isolated bone marrow carcinomatosis of poorly differentiated gastric adenocarcinoma in a young male is rare and associated with poor prognosis.
