Abstract

Background: Eccrine poroma (EP) is an adnexal benign tumor arising from the eccrine duct epithelium. The appearance of EP can mimic benign and malignant skin tumors, thus often making the diagnosis delayed or inaccurate. Case Illustration: We report two cases of EP, with clinical and dermoscopic features mimicking Bowen’s disease, verruca vulgaris, pyogenic granuloma, skin metastases of breast cancer, and amelanotic melanoma. Both patients were surgically excised and biopsied. Histopathology examination of both cases revealed eccrine poroma. Discussion: Both cases showed similarity with the theories, that EP is most found in middle age population and its predilection on extremities. The dermoscopy appearance of the first patient showed two major components, multiple red dots and lacunae mimicking glomerular vessels, and multiple whitish halos-likekeratosis. Red dots with whitish halos can be seen in dermoscopy of verruca vulgaris, while glomerular vessels and keratosis is usually found in Bowen’s disease. The dermoscopy examination of our second patient only showed some loop hemorrhagic and thrombosed vessels, which are quite inconclusive. Diagnoses were made with histopathology examination which revealed similar pattern of eccrine poroma in both cases. Conclusion: EP is a prominent mimicker, often misdiagnosed because it is uncommon in clinical practice, has variable clinical presentations and dermoscopic appearances. Hence, recognizing and diagnosing this disease becomes a challenge for dermatologist.

Abstract

Background: Basal cell carcinoma (BCC) is a malignant, slow growing, and locally invasive skin tumor. Advanced and neglected BCC may invade adjacent structures. The 5-year recurrence rates of facial BCCs are 4.1% after excision and 2.5% after Mohs Micrographic Surgery (MMS). The number of BCC cases invading the bones of the head and neck region is limited. Case Illustration: A 75-year-old male complained of bleeding and ulcer enlargement on the right cheek expanding to the right nasal ala for 1 month. The patient had a history of an enlarged and painful lenticular nodule with a hyperpigmented spot that appeared 10 years ago on the right cheek and was diagnosed as BCC. The patient was treated with a wide excision having a negative pathological margin 3 years ago. He noticed that the similar lesion reappeared at the same location 2.5 years ago. Post-operative histopathological results showed nodular infiltrative BCC and maxillary bone invasion. Discussion: Based on history taking, physical examination, and diagnostic evaluation, the diagnosis of the patient was recurrent nodular infiltrative BCC. The final histopathology confirmed that tumor cells invaded the maxillary bone. After considering the treatment options, the patient opted to proceed with radiotherapy. Conclusion: Recurrent nodular BCC with invasion to the maxillary bone is a rare and interesting case. Among 140 BCC cases that we treated with MMS in our hospital from June 2014 to September 2019, this case is the first recurrent BCC with maxillary bone invasion.
