Papillary cystadenocarcinoma of the parotid gland: a rare sub-variant of salivary gland adenocarcinoma

Papillary cystadenocarcinoma of the salivary gland is a very rare malignant neoplasm accounting for only 2% of all salivary gland lesions. In 1991 it was first included as a separate entity in the World Health Organization (WHO) classification of salivary gland tumors and in 2017 WHO Classification, the tumor was clubbed as a sub-variant of adenocarcinoma, not otherwise specified. It most commonly occurs in the major salivary glands. Herein we report a case of salivary papillary cystadenocarcinoma in a 54-year-old female, who presented with rapid enlargement of the right parotid swelling. Based on radiology and fine-needle aspiration cytology, a working diagnosis of the malignant tumor involving the superficial lobe of the right parotid gland was made. In view of the malignant nature of the swelling, superficial parotidectomy was done. The histopathology and immunohistochemistry of the mass confirmed the diagnosis of papillary cystadenocarcinoma of the right parotid. With the revised 2017 WHO classification of salivary gland tumors, it is important to report all rare subtypes in order to understand their biology and behavior.

Giant cell reparative granuloma of the nasal cavity: a rare site of presentation with review of literature

Giant cell reparative granuloma (GCRG) was first described in the 1950s. It is an uncommon and benign reactive tumor that is believed to occur after trauma or inflammation. It most commonly occurs in the maxilla and mandible and rarely affects the nasal cavity. It is often seen in children and during the second to third decades of life, predominantly seen among females. Histopathologically, GCRG shows many osteoclast-like multinucleated giant cells scattered in a background of mononuclear stromal cells and spindle-shaped fibroblasts also associated with areas of hemorrhage. The distinction between GCRG and giant cell tumors (GCT)is crucial since both have a similar clinical and histological presentation, but both have different management. GCTs have malignant potential, may metastasize, and have a high rate of recurrence. Surgical excision is the mainstay therapy of GCRG to ensure a low rate of recurrence. Here we discuss two cases GCRG, both presenting as nasal mass.

Angiomyolipoma of the broad ligament

Angiomyolipoma is a benign mesenchymal neoplasm of the renal parenchyma, accounting for 1% of all renal parenchymal tumors. However, this entity may rarely occur in extrarenal sites. Extrarenal angiomyolipoma has been documented in various sites of the body, but angiomyolipoma of the broad ligament was reported in only two cases. We report the reputed third case of angiomyolipoma of the broad ligament in a 33-year-old female, who presented clinically with abdominal distension. With a working diagnosis of low-grade neoplasm, an en-bloc excision of the left broad ligament mass was performed. Based on histopathology and immunohistochemistry, a diagnosis of the classical variant of angiomyolipoma of the left broad ligament was made. The post-operative period was uneventful with no recurrence after 6 months of follow-up.

Carcinoma cervix de novo with widespread cutaneous/subcutaneous metastasis: A rare case report

Cancer of the uterine cervix is one of the leading gynecological malignancies of developing nations including India. A 45-year-old female presented with menstrual irregularities and other nonspecific symptoms. After initial workup, she was diagnosed with carcinoma cervix, Stage IV A, while she was being planned to take up radical concomitant chemoradiotherapy, she developed widespread nodules over various sites over the body, which were histopathologically proven as metastatic lesions. She was treated with a palliative intent by radiotherapy and chemotherapy. Only a few such cases have been reported in the literature with variable outcomes. These rare presentations should be thoroughly worked up and studied to know more about their biological behavior.
