Histopathological spectrum of scalp tumors: Analysis with review of literature p. 25
Monica Kumbhat, Leena Dennis Joseph, B Subalakshmi, V Vidhya
Purpose/Background: The scalp is the part of the body, which frequently presents with a wide variety of lesions, which may range from congenital, inflammatory, post traumatic, and neoplastic. Swellings and cysts are common occurrences. Both benign and malignant tumors are located in the scalp and correct diagnosis is needed for appropriate management. Materials and Methods: This is a retrospective study, where we reviewed surgically excised swellings in the scalp, over a duration of 6 years. The data were obtained from the records in pathology department, in a tertiary care hospital in South India and clinical inputs were obtained from the hospital records. These were categorized primarily into benign and malignant lesions. The benign lesions were further classified as cystic lesions, vascular lesions, epidermal proliferations, and skin adnexal tumors. The malignant lesions were sub categorized as primary or secondary (metastatic). Results: One hundred cases of histopathologically proven diverse cases of scalp swellings were included. Majority of them were benign, accounting for 77% with rest of them being malignant (23%). Among these 100 cases, 99 cases primarily originated in the scalp and only one case was a secondary tumor. Pilar cysts accounted for about 18 cases, of which 6 cases showed calcification. Vascular tumors and skin adnexal tumors played a major role. The most common malignant tumor was squamous cell carcinoma. Excision with clear margins was the mode of treatment for majority of the cases, with follow-up oncologist referral, when required. Conclusions: Recognition of the correct diagnosis aids in appropriate management of the patient, allaying the fears and concerns of the patient.

“Primitive myxoid mesenchymal tumor of infancy” - A rare childhood soft-tissue tumor of the mandible p. 29
Gittwa Vatsaraj Kottangal, Chaya Prasad, Annie Jojo
Primitive myxoid mesenchymal tumor of infancy (PMMTI) is an extremely rare soft-tissue tumor of childhood. We report a case of an 18-month-old male child diagnosed with PMMTI of the mandible. Till now <30 cases had been reported in the English literature. Histologically, the tumor consists of primitive spindle/polygonal cells dispersed in a myxoid background with delicate blood vessels. Immunohistochemically, tumor cells are positive for vimentin and negative for all other myoid, neural, epithelial, vascular, and neuroendocrine markers. This tumor was previously included under the diagnostic categories of congenital infantile fibrosarcoma or infantile fibromatosis. Increased awareness of this novel entity is a must as its biological and chemosensitive nature is vastly different from its differentials. Recent immunohistochemical stains and cytogenetic studies have helped to differentiate PMMTI from the other tumors of similar morphology.

Epithelial myoepithelial carcinoma arising in a pleomorphic adenoma p. 33
Daphne Fonseca, M Shankar, Chandrasekhara S Rao, Hemanth Kumar Nemade
Epithelial–myoepithelial carcinoma (EMC) is a rare and low-grade malignant tumor of the salivary gland. We present a case of a 37-year-old male with good general condition with swelling in the right preauricular region for the past 3 years measuring 3 cm × 2 cm with intact facial nerve. This patient had a history of preauricular sinus excision surgery 15 years ago. EMC mostly occurs in elderly females. Rarity of our case is in the fact that it has occurred in a middle-aged male with histologic evidence of preexisting pleomorphic adenoma.

Infected nasolabial cyst: A rare entity with unusual presentation p. 36
Purnima Paliwal, Shashikant Singh, Jyoti Mishra, Devender Singh Chauhan
Cystic lesions of the anterior maxilla and ala of the nose are both odontogenic and nonodontogenic. Nasolabial cyst is an uncommon cystic lesion in this location, which clinically presents with progressive cystic swelling and nasal obstruction. Diagnosis is based on clinical/radiological findings and confirmed by histopathological examination of the excised cyst. Herein, we present a case report of nasolabial cyst in a 50-year-old female who presented with swelling over anterior maxilla.
