Sir,

Gamna-Gandy (G-G) bodies are sclerosiderotic foci, commonly found in spleen. They are also known as siderotic nodules or tobacco flecks. [1] They are defined as spheroidal yellow-brown foci of dense fibrous tissue and collagenous fibers composed of calcium and hemosiderin pigments. These siderotic nodules were noticed since early 20th century. They were first seen in the spleen. The earlier erroneous notion was it may be due to fungal infection because of the presence of unusual "bamboo-like and articulated" fibers in these lesions often mimicking fungal hyphae. They occur because of the organization of small hemorrhages with accumulation of hemosiderin. Apart from spleen, G-G bodies are described in atrial myxomas. Rarely they have been reported in other organs like lymph nodes, thymoma, follicular adenoma of thyroid, colorectal polyp, renal cell carcinoma, and central and peripheral nervous system neoplasms. [2],[3],[4],[5]

Recently, we encountered G-G bodies in a case of adenomatous goiter of thyroid. This patient was a 64-year-old male who had a huge swelling of the thyroid, measuring 25 cm Χ 15 cm, present since the last 20 years. He underwent fine needle aspiration cytology (FNAC), where it was reported as adenomatous goiter. Subsequently, the patient underwent total thyroidectomy that revealed features of adenomatous goiter. One focus showed presence of typical G-G bodies [Figure 1],[Figure 2] and [Figure 3]. Perls' stain was done and it showed positive [Figure 4]. This patient has undergone FNAC that might have resulted in hemorrhage, subsequently, leading to the formation of G-G bodies. Though FNAC is a routine procedure in thyroid lesions, G-G bodies are not routinely reported. So the pathogenesis of G-G bodies remains an enigma.
