Involvement of the bilateral submandibular glands and thyroid by the same lymphoma simultaneously has been reported in the literature. However, two different types of lymphomas presenting simultaneously at different sites have never been reported. This case report highlights this rare occurrence. A 65‐year‐old female, a known case of Hashimoto’s thyroiditis with raised anti‐TPO antibodies, presented with thyroid swelling for 1 year and bilateral submandibular swelling for 3 years. FNAC and flow cytometry showed features of mucosa‐associated lymphoid tissue lymphoma in the thyroid gland, whereas the bilateral submandibular glands showed features of diffuse large B cell lymphoma. Histopathology and immunohistochemistry from the submandibular swelling led to similar diagnoses as the flow cytometry.
