Clear cell carcinoma of soft palate- A case report.

Clear-cell carcinoma (CCC) of the salivary gland is a very rare malignancy. It is recently introduced in the WHO classification of salivary gland tumors. CCC is considered a low-grade tumor, which is commonly seen in elderly females. The most common intraoral sites affected by CCC are palate and tongue. CCC comprises 1% of all salivary gland tumors. CCC has a silent course and a limited nodal metastasis. A hyalinized variant of CCC has good prognosis and requires wide surgical excision with or without adjuvant radiotherapy. Microscopically, it is characterized by the presence of nests of glycogen-rich monomorphic clear cells within a hyalinized stroma. Immunohistochemistry analysis of CCC depicts tumor cells which are positive for epithelial markers and negative for S-100. Here, we report the case of a hyalinized CCC of minor glands of the palate which was misdiagnosed as poorly differentiated squamous cell carcinoma.

Intranasal tooth: ectopic eruption 1 year after maxillofacial trauma.

Injury to the permanent central incisors due to trauma in the maxillofacial region, though common, may result in an uncommon sequel. We report a case of traumatic injury in a 5-year-old child with displacement of the tooth bud into the nasal floor. The identification of ectopic tooth buds poses little diagnostic challenge due to the available imaging facilities, however, in the present case the ectopic bud remained unnoticed and resulted in ectopic eruption of the tooth in the nasal cavity 1 year later. This report highlights a rare case of nasal eruption of a permanent tooth and places stress on the need for close attention to detail during maxillofacial trauma for early detection and proper management.

Cutaneous sinus tract in association with traumatic injury to the teeth.

The present case report is of trauma episode of the lower anterior teeth, causing pulpal necrosis with periradicular periodontitis, resulting in the occurrence of cutaneous sinus tracts (fistula). Previous misdiagnosis and inappropriate medical treatment were ineffective. Only when properly referred to dentists, the differential diagnosis was made. The guideline to diagnose cutaneous sinus tracts (fistula) is based mainly on accurate pulp sensitivity tests of the involved traumatized teeth. Intraoral and dental examinations are critical in making the diagnosis. The case presented here shows that cutaneous odontogenic sinus tracts associated in traumatized teeth, even in absence of caries or tooth fracture. How to cite this article: Mishra R, Khan TS.
