Treatment of advanced malignant eccrine poroma with locoregional chemotherapy.

Malignant eccrine poroma is a rare disease with approximately 200 cases reported in the literature. Regional cutaneous and systemic metastases are rarely observed and their management has been generally unsuccessful. We report on a case in which topical 5-fluorouracil application and intra-arterial chemotherapy with docetaxel resulted in a histologically confirmed complete response of multiple regional skin metastases for more than 2 years. Despite intravenous administration of docetaxel, slow progression of systemic disease was observed.

Eccrine porocarcinoma arising in two African American patients: distinct presentations both treated with Mohs micrographic surgery.

Abstract Background Eccrine porocarcinoma (EPC) is a rare, malignant adnexal tumor that has been reported only three times specifically in African American individuals. Diagnosis and treatment of EPC is important, given the 20% local recurrence and regional metastatic rates. However, no standard of care has been developed to guide effective treatment. Methods We report two distinct clinical presentations of EPC, both in African Americans, and discuss a review of the literature. Results The neoplasms were successfully removed from both patients by Mohs micrographic surgery. Conclusions These two cases illustrate that EPC can have a variety of presentations and can occur in African Americans. Although there is no standard of care for treating EPC, Mohs is becoming a common technique of removing these lesions.

Antitumour activity of paclitaxel and interferon-alpha in a case of metastatic eccrine porocarcinoma.

BACKGROUND: Eccrine porocarcinoma (EP) is a rare malignant tumour arising in the acrosyringium, with about 50% of the cases developing local recurrence or metastatic disease. No standard therapy protocols for metastatic disease exist. In the past, only short remissions were achieved by applying combinations of cytotoxic agents, which were associated with severe side-effects. AIM OF THE STUDY: In the case reported here, the aim was to find a protocol with fewer side-effects for a patient who was not willing to undergo extensive polychemotherapy. SUBJECT: A 67-year-old male patient with local recurrence and regional lymph node metastases after resection of EP was treated with a combination of interferon-alpha (IFN-alpha) 9 million units s.c. three times per week and paclitaxel 100 mg/m(2) weekly i.v., which shows a side-effect profile similar to taxotere and is used in the treatment of a variety of neoplasms such as advanced squamous cell carcinoma. MAIN OUTCOME: This less aggressive treatment was tolerated well and the patient responded with minor remission and long-term stable disease.

Eccrine porocarcinoma.

Eccrine porocarcinoma is a malignant tumor of eccrine sweat glands. It is a very rare, slow growing tumor and clinically resembles other skin cancers. We report a case and review its clinical and pathological features. These tumors have a propensity for local recurrence, and wide excision with negative margins is recommended.

Metastatic eccrine porocarcinoma: a 5.6-year follow-up study of a patient treated with a combined therapeutic protocol.

BACKGROUND: Metastatic eccrine porocarcinoma (EP) is an uncommon, malignant, and potentially lethal neoplasm that arises from the eccrine sweat glands. OBJECTIVE: To present the 5.6-year follow-up study of a male patient with metastatic EP, highlighting the widespread cutaneous involvement and the response to the treatment carried out. METHODS: We describe the evolution of the tumor and the combined therapy carried out and review the treatments employed in previously reported cases, comparing them with ours. RESULTS: The patient developed multiple cutaneous and regional lymph node metastases 15 months after surgical excision of the primary tumor. He was treated with prophylactic lymphadenectomy, radiotherapy, and oral isotretinoin, subsequently substituted by tegafur. We have not found evidence of distant metastases after a 5.6-year follow-up. CONCLUSIONS: The optimum treatment for metastatic EP is not standardized, and the results obtained to date were generally poor. In this context, we consider it of interest to highlight the response of our patient to the therapeutic regime employed, which may be advantageous in future cases of this rare tumor.
