In the present study 27 cases of Nodular goiter on Touch imprint Cytology were found to be Nodular goiter in 23 cases, Follicular adenoma in 2 cases and Papillary carcinoma in 2 cases.
Histologically, MNH has nodular or lobulated architecture with two main cell subpopulations: one type consists of polygonal cells with round nuclei and vacuolated cytoplasm as a result of abundant glycogen, while the second type of cells is characterised by oval nuclei and dark basophilic cytoplasm with infiltrative or invasive growth patterns into the dermis and surrounding tissues.
Pathology from this specimen showed extensive effacement of the normal architecture by an atypical predominantly diffuse but focally vague nodular polymorphous lymphoid infiltrate composed of a mixture of small, medium, and large cells.
The pulmonary presentation may be tracheobronchial, nodular parenchymal [amyloidoma], or diffuse parenchymal [interstitial/diffuse alveoloseptal] [2, 3].
Sclerosing angiomatoid nodular transformation (SANT) of the spleen is a rare benign vascular lesion with unknown etiopathogenesis and with definite features of imaging, histopathology, and immunohistochemistry.
