Fundal Variant of Adenomyomatosis of the Gall Bladder: An Uncommon Entity.

Adenomyomatosis of the gallbladder is a benign and degenerative condition of the gallbladder. It is an incidental finding in gall bladder specimens resected for chronic cholecystitis or cholelithiasis. It frequently occurs after 3rd or 4th decade of life and is often an incidental finding in cholecystectomy specimens resected for chronic cholecystitis or cholelithiasis. Patients with adenomyomatosis are usually asymptomatic it can be classified into three types: Segmental, fundal and diffuse types. The fundal variant is uncommon compared to the other two types. Here, in we present a case of a fundal variant of adenomyomatosis of the gall bladder in a 65-year-old male patient.

Pilomatricoma Unmasked on Fine Needle Aspiration Cytology.

Pilomatrixoma is an uncommon adnexal tumor with heterogeneous features can mimic various malignancies and contributes to false positive diagnosis on cytology. It is an uncommon, slow growing, benign skin adnexal neoplasm of hair matrix origin initially described by Malherbe and Chenantais. This tumor is predominantly found in the head and neck region, and presents as a small, asymptomatic, slow-growing dermal, subcutaneous, solitary lesion. More than 50% of these tumors are known to occur in the second decade of life and is often misdiagnosed clinically. Cytological features pose a diagnostic challenge although the histological features are very well delineated. This paper presents the cytological features in two cases outlining the importance of the clinicopathological features that need to be considered for an accurate diagnosis. Awareness of its varied cytologic features and clinical presentation can avoid misdiagnosis.

Odontogenic Myxoma Involving the Maxilla: Case Report of a Rare Entity.

Odontogenic myxomas (OMs) are rare, benign, slow-growing tumors that may arise in the maxilla. They are known to have a female predilection and present as a painless mass commonly in the second or third decade of life, comprising 3-6% of all odontogenic tumors. They show a locally aggressive behavior, are radioresistant tumor and hence the need for early recognition and surgical resection. A high rate of recurrence has also been noted owing to its infiltrative pattern of growth and lack of capsule. Clinical and radiological aspects of maxillary OMs are not conclusive hence it is necessary to have a histopathological exam for the final diagnosis. We present a case of OM involving the maxilla in a 51-year-old female patient. The various histopathological differentials are also discussed.
