ABSTRACT
Nasal sebaceous carcinoma is an extremely rare cutaneous malignancy. We present the case of an 86-year-old female who had a skin nodule with surface telangiectasia on the right ala of the nose. The lesion had been removed and has been reconstructed with an advancement rotational flap with a minimal residual defect. Upon histopathological examination, the lesion was diagnosed with sebaceous carcinoma. The patient was followed up because of the high rate of recurrence as well as metastatic potential. No recurrence occurred during 4 years of follow-up, and the patient was unwilling to reconstruct the remaining alar defect. We present a rare skin cancer case that could be encountered during the head and neck examination by oral and maxillofacial surgeons. By reporting this case, we aimed to raise the awareness and familiarize clinicians with these less common lesions.
ABSTRACT
BACKGROUND: Esophageal leiomyosarcoma (LMS) is a rare tumor that constitutes less than 1% of all malignant esophageal tumors. Concurrent occurrence of esophageal leiomyosarcoma with squamous cell carcinoma (SCC) is even rarer than isolated leiomyosarcoma. CASE PRESENTATION: In this report, we present a case of concurrent leiomyosarcoma and SCC in a 64-year-old woman presenting with vomiting and solid dysphagia, which has not been properly diagnosed following several referrals and diagnostic modalities. At last Exploratory laparotomy with gastric pull-up was performed in addition to radical laryngectomy with partial resection of the esophagus and subtotal thyroidectomy. Pathologic evaluation of the surgical specimen showed concurrent LMS (5.2 × 4.5 × 3 cm) and SCC (1.5 × 0.6 × 0.6 cm) at the same anatomical level in the proximal esophagus. CONCLUSIONS: This study proposes the importance of using ancillary diagnostic tests such as immunohistochemistry (IHC) to diagnose less common cases such as concurrent LMS and SCC.
