Hyalinizing clear cell carcinoma of parotid, intricacies of management:a rare case report

Hyalinizing clear cell carcinoma (HCCC) usually affects minor salivary glands. It rarely occurs in major salivary glands. HCCCis difficult to diagnose in Fine Needle Aspiration cytology (FNAC). The possibility of metastasis from other primary sites should be rejected during the management of these tumors. An elderly manpresented with insidious onset, and gradual progressive painless swelling arising from the deep lobe of the parotid gland. FNAC, which was performedtwice with UltrasoundGuidance(USG), could not provide much detail about the type of tumor. Total conservative parotidectomy was conducted. These rare tumors cause significant challenges to physicians. Thehigh index of suspicion and combined efforts ofthe multidisciplinary team are pivotal in management.

An unusual case of hyalinizing clear cell carcinoma in a sinonasal cavity and cranial base

Hyalinizing clear cell carcinoma (HCCC) is a rare, predominantly minor salivary gland tumor. Most of these tumors occur in the oral cavity, mainly the palate and tongue. Primary localization of the tumor in the region of the nasal cavity and paranasal sinuses is extremely rare and, with only a few cases reported in the literature so far. We present an extremely rare case of a 61-year-old woman with hyalinizing clear cell carcinoma (HCCC), occupying the left posterior nasal and nasopharyngeal cavity, as a primary tumor location. The patient total recovery was uneventful, and she is now free of disease at three years postoperative follow-up.
