Recurrent trichilemmal carcinoma of the periorbital region treated with IMRT radiotherapy: A case report and a review of literature

RATIONALE

Trichilemmal carcinoma (TLC) is a rare malignant cutaneous adnexal tumor usually accept surgery. This report describes an elderly patient with recurrence TLC of the periorbital region after surgery who was subsequently treated with IMRT radiotherapy. After 2-years follow-up visit, there was no progress or metastasis.

INTRODUCTION

TLC is a rare malignant cutaneous adnexal tumor. It usually occurs on sun-exposed areas in elderly people but rarely occurs in the periorbital region. Most cases accept surgery or micrographic Mohs surgery. Recurrence or metastasis of this neoplasm was seldom reported in the medical literature after enough tumor-free margin surgery. And radiotherapy was seldom reported in the treatment for patients of TLC.

PATIENT CONCERNS

Here we report an elderly patient with recurrence TLC of the periorbital region after surgery who was subsequently treated with radiotherapy with a total dose of 66 Gy. Two years later, the patient was admitted head, neck, chest, abdomen CT scan, and no progress or metastasis was detected after 2-years follow-up.

DIAGNOSIS

Trichilemmal carcinoma of the periorbital region.

INTERVENTIONS

We describe the clinical characteristics, pathological features, and choice of examination methods of a patient with TLC in the periorbital region. And we use the radical radiotherapy to treat this case.

OUTCOMES

There are no progress or metastasis after 2-years follow-up.

CONCLUSION

Radiotherapy is a good option for patients with TLC if the patient refuses surgery or fails to achieve a satisfactory tumor-free margin or relapses after surgery.

Malignant proliferating trichilemmal tumor of the scalp: report of 4 cases and a short review of the literature

Malignant proliferating pilar tumors are very rare adnexial lesions that can be confused with other skin neoplasms. The authors present four patients with malignant proliferating trichilemmal tumors located on the scalp. A review of the literature search for malignant proliferating pilar tumors and treatments was performed.

Management of 3 Proliferating Pilar Tumors: Definition, Differential Diagnosis, and Treatment Options

A proliferating pilar tumor is a rare skin neoplasm that arises from the outer root sheath of a hair follicle. Presentation varies widely, as the tumor can be benign or malignant and has a high probability of recurring after excision. We report our experience managing 3 proliferating pilar tumors with different clinical presentations and pathology findings at Hospital de San José, Bogota, Colombia.
