Actinic keratosis is a common skin disorder in elderly patients with fair complexions. It is caused by exposure to ultraviolet light. If left untreated, actinic keratosis may progress to squamous cell carcinoma. The metastatic potential and prognosis vary with the type and location of the lesion. Several approaches to treatment are available, including local destruction, excisional surgery, Moh...
DESCRIPTION A 67-year-old male patient presented with basal cell carcinoma of the superior helix of the left ear. He underwent Mohs surgery with complete tumor excision resulting in an approximately 2.5 cm open wound with exposed cartilage. The defect was reconstructed with an Antia-Buch chondrocutaneous advancement flap.
The appropriate use criteria process synthesizes evidence-based medicine, clinical practice experience, and expert judgment. The American Academy of Dermatology in collaboration with the American College of Mohs Surgery, the American Society for Dermatologic Surgery Association, and the American Society for Mohs Surgery has developed appropriate use criteria for 270 scenarios for which Mohs mic...
IMPORTANCE Surgical excision of skin cancer is a common treatment, yet the proper surgical margin remains unclear. This study reviews data on lesions and their margins as defined by Mohs micrographic surgery. OBJECTIVE To review margins as defined by Mohs micrographic surgery. DESIGN Retrospective review of data from patients with skin cancer. SETTING Academic medical center. PARTICIPAN...
Enlarged eccrine porocarcinoma of the knee was encountered as a hemorrhagic bulky tumor. After controlling bleeding with Mohs' paste, local excision of the lesion was the mainstay of treatment. Pathological examination revealed poroid cells, cuticle cells, and prickle cells cancer components, suggesting that malignancy must be excluded by resection.
The adnexal tumours are a very heterogeneous group of lesions, more and more studied in the literature. The squamoid eccrine ductal carcinoma (SEDC) is a rare malignant variant that combines ductal structures with squamous differentiation. We report a case of dermoscopic and histological diagnosis of SEDC, treated with Mohs Surgery and with no recurrence of a tumour after 12 months of follow up.
Hidroacanthoma simplex is a rare intraepidermal neoplasia that arises from the acrosyringial portion of the eccrine duct. Malignant transformation of hidroacanthoma simplex is reported in the literature and the treatment is performed with wide excision or Mohs micrographic surgery. We report the first case successfully treated with cryosurgery with a long-term follow up.
BACKGROUND In nonmelanoma skin cancer, the clinically visible portion may represent a small fraction of microscopic tumor spread. Previous studies have examined individual risk factors for subclinical spread based on patient and tumor characteristics. However, these risk factors have not been prioritized or studied in combination. OBJECTIVE To identify the most predictive risk factors for ext...
