Salmon calcitonin - a boon in the management of central giant cell granuloma p. 197 D Nivethitha Gangai, G V. Murali Gopika Manoharan DOI:10.4103/srmjrds.srmjrds_50_18 Central giant cell granuloma is an uncommon, benign, proliferative lesion of unknown etiology, most commonly affecting anterior mandible of younger age group. Early diagnosis may be of benefit to the patient as conservative treatment modalities may be used as compared to radical surgical treatment. Calcitonin as a therapy for central giant cell granuloma of the jaws is a promising alternative to surgical curettage, particularly for larger lesions. We report a case of central giant cell granuloma of mandible in a 14-year-old female patient, who is being treated solely with intranasal spray of salmon calcitonin for 14 months showing greater results.

Schwannoma of the base of the tongue mimicking fibroma p. 202 Sukhvinder Singh Rana, Neera Ohri DOI:10.4103/srmjrds.srmjrds_35_18 Schwannoma is a slow-growing benign tumor of the nerve sheath. It originates from the Schwann cell of the peripheral, autonomic, and cranial nerve. It is usually a single, circumscribed, firm, painless lesion of variable size. 25%–40% of all schwannomas are considered to affect the head and neck region, with the parapharyngeal space being the most common location. Only 1% of cases are intraoral. The treatment of choice is surgical excision of the tumor. Schwannomas do not show recurrence if completely excised. We report a case of schwannoma of the base of the tongue mimicking fibroma.

Clear-cell squamous cell carcinoma: An uncommon variant of very common malignancy in the head and neck p. 136 Lopa Mudra Kakoti, Debanwita Mahanta, Jagannath Dev Sharma, Zachariah Chowdhury DOI:10.4103/ijohs.ijohs_23_18 Clear-cell squamous cell carcinoma (SCC) is an extremely rare and incompletely understood entity. Clear-cell change occurs due to cytoplasmic accumulation of glycogen, water, intermediate filaments, immature zymogen granules, or a paucity of cellular organelles. Clear-cell change can be seen in any of the neoplasms, but as pure form variant, it is difficult to find in head-and-neck SCC. The World Health Organization has recognized clear-cell SCC as separate entity at other few sites such as penis but not in the head-and-neck SCC, and these are known to aggressive variant. We, hereby, present a case of clear-cell variant of squamous carcinoma in lower gingivobuccal mucosa in a 59-year-old male patient. Histopathology showed sheets of clear cell separated by fibrous s

We, hereby, present a case of clear-cell variant of squamous carcinoma in lower gingivobuccal mucosa in a 59-year-old male patient. Histopathology showed sheets of clear cell separated by fibrous septa and foci showing squamous cells with malignant features. Periodic acid–Schiff and immunohistochemistry (IHC) were done to rule out differentials of clear-cell variants of different sites such as salivary gland, odontogenic origin, and cutaneous adnexal origin. To establish the prevalence, biological nature, significance, and clinical course of clear-cell SCC in the head-and-neck region, more number of case reports are expected to be published in future. We concluded by emphasizing on the need of further analysis of all clear-cell tumors in the head and neck with histochemistry and IHC investigations to arrive at the proper diagnosis.

The course of double mandibular canal - confront to dentist p. 133 Jayasheela Mallappa, Neeharika Sree, B H Dhanya Kumar, Dhoom Singh Mehta DOI:10.4103/ijohs.ijohs_40_18 The mandibular canal is usually a single canal that begins with mandibular foramen on the medial surface of the ascending mandibular ramus. It transmits the inferior alveolar artery, vein, and the inferior alveolar nerve. The identification of the mandibular canal and its anatomic variations is of great importance in many branches of dentistry, especially in implant dentistry. Sometimes, there may be variations in the normal anatomic structures; one of the rarest among them is double mandibular canal. The clinician should be aware of such variations to avoid complications during the treatment. In the present case report, we have discussed about a case with double mandibular canal and the complications that can arise during the treatment.

Actinomycotic infection of the tonsils: A case report and review of the literature p. 129 Stavanger Singh Bakshi, Ramiya Ramachandran Kaipuzha, Suriyanarayanan Gopalakrishnan, A Govindarajan DOI:10.4103/ijohs.ijohs_43_17 Actinomycotic infections of the head and neck, although fairly uncommon, represent an important entity because of its varied presentation, difficult diagnosis, and long course of treatment. A 20-year-old female presented with throat pain and difficulty in swallowing for 1 year. Examination revealed a Grade IV enlargement of the left tonsil. The patient underwent tonsillectomy, and the postoperative histopathology revealed actinomycosis. Actinomyces is anaerobic filamentous bacteria which are known to colonize as commensals in tonsillar crypts which on histology show an outer zone of granulation tissue and a central zone of necrosis containing many sulfur granules that represent microcolonies of Actinomyces. Actinomycosis of the head-and-neck region is a significant

Actinomyces is anaerobic filamentous bacteria which are known to colonize as commensals in tonsillar crypts which on histology show an outer zone of granulation tissue and a central zone of necrosis containing many sulfur granules that represent microcolonies of Actinomyces. Actinomycosis of the head-and-neck region is a significant entity because it can mimic other common lesions, especially in the oropharynx. In cases of recurrent tonsillitis and tonsillar hypertrophy, tonsillectomy is the treatment of choice, and histopathological examination of resected tissue is strongly advocated. This report supports the view that Actinomyces may have a causal association with recurrent acute tonsillitis and tonsillar hypertrophy.

unusual presentation of mucoepidermoid carcinoma with review of literature p. 120 Gadadasu Swathi, Tatapudi Ramesh, Moturi Kishore, Govind Raj N Kumar DOI:10.4103/ijohs.ijohs_24_18 Head-and-neck cancers constitute about 30% of cancers in India, of which salivary gland tumor such as mucoepidermoid carcinoma (MEC) was the most common malignant salivary gland tumor. The parotid gland was the most common site of origin in both benign and malignant tumors, followed by submandibular and sublingual glands. Salivary gland tumors comprise a morphologically diverse group of rare tumors. Their multifaceted clinical presentation, varied morphologic configuration, and relatively unpredictable prognosis attract significant medical interest. Here is a rare case report of an asymptomatic swelling in the cheek region which was thought to be pleomorphic adenoma at the outset which on further investigations proved as MEC of early detection.
