Introduction: Basal cell nevus syndrome (BCNS) (Gorlin-Goltz syndrome or Nevoid basal cell carcinoma syndrome) is a rare inherited multisystem and tumor-predisposing disorder caused by the patched tumor suppressor gene mutations and suppressor of fused gene. Its diagnosis follows a set of criteria based on specific cutaneous features and radiologic findings. Although an autosomal dominant disorder with a high degree of penetrance, BCNS has variable expression making its diagnosis difficult. The limited epidemiologic data among Asians especially in the Philippines hamper early detection or cause frequent misdiagnosis of the condition. Case report: A 56-year-old Filipino female with Fitzpatrick skin type V presented with early onset multiple basal cell carcinomas and bilateral palmoplantar pits. Radiologic investigation reveals odontogenic keratocyst, calcification of the falx cerebri, bridging of the sella turcica, bifid/splayed ribs and vertebral anomalies. The patient exhibits coarse facial features and bilateral cataracts. Cranial computed tomography scan shows cerebrocerebellar atrophy with ventricular dilatation. Management included wide excision of the nodular basal cell carcinomas (BCC), application of 5-flourouracil cream on the superficial BCC and electrodessication and curettage of the smaller lesions. Oral acitretin was also prescribed. Conclusion This is a case that highlights the approach to diagnosis, clinical features and management of BCNS in a Filipino patient. Since various phenotypic presentations may exist among dark-skinned individuals, early diagnosis poses a challenge among physicians. Epidemiologic and prevalence studies among Filipinos may be done to aid in the diagnosis and early management of this rare genodermatosis.

Objective: We aim to determine the association between preoperative CT scan findings of thyroid cartilage invasion, cricoid cartilage invasion, and paraglottic space involvement with tumor extension to the thyroid gland on final histopathology among patients with laryngeal squamous cell carcinoma (SCC) in a tertiary hospital in the Philippines. Methods: Patients with histopathologically-confirmed laryngeal SCC who underwent total laryngectomy with thyroidectomy while admitted at the public ward of the Department of Otorhinolaryngology, Philippine General Hospital, from January 2013 to December 2019 were included. CT scans were reviewed by 2 blinded independent radiologists. CT scan data including subsite/s involved, thyroid cartilage/cricoid cartilage erosion, paraglottic space involvement, thyroid gland involvement, and thyroid gland involvement on final histopathology were gathered. Clinicopathologic data such as age, T Stage, early tracheostomy, and time between CT scan and surgery were also collected and analyzed. Fisher’s exact test was computed for both clinicopathologic and CT scan data with a significant value having p<0.05. Cramer’s V and phi coefficient were computed for nondichotomous and dichotomous variables, respectively. Odds ratio was also computed for dichotomous variables with p<0.05 on Fisher’s exact test. Results: Fifty-nine (59) men and 4 women were included, aged 43 to 81 years old. Most patients were classified as T3 (n=18) and T4 (n=41) (total=93.7%), with most having transglottic primary tumors (n=29, 46%), and only 8 (12.7%) patients having subglottic tumor involvement on final histopathology. Thyroid cartilage erosion or invasion were noted in 63.4% (n=40) of patients’ CT scans and 58.7% (n=37) of patients’ final histopathology reports. Cricoid cartilage and paraglottic space involvement were often not reported on final histopathology results. Thyroid gland involvement was only noted in the final histopathology reports of 5 patients (7.9%). Significant association between cricoid cartilage findings (p=0.032, Cramer’s V=0.318) or thyroid gland involvement on CT scan (p=0.018, Phi=0.384; OR 13 95% CI 1.797, 94.035) with thyroid gland involvement on final histopathology was noted. The rest of the variables had no significant association with thyroid gland involvement on final histopathology. Conclusion Cricoid cartilage involvement (erosion or invasion) and thyroid gland involvement on CT scan are associated with thyroid gland involvement on final histopathology in patients with laryngeal SCC. Patients with these CT scan findings may stand to benefit more from thyroidectomy to ensure good margins of resection.
