Introduction

Background

Carcinomas of the eccrine sweat gland represent a rare group of tumors with potential for local destruction and metastasis. High recurrence rates have been reported following conventional surgical excision of eccrine carcinomas. The specific classification of eccrine carcinomas is both complex and nebulous, in large part because of the paucity of reported cases but also because many of these tumors show little histologic resemblance to mature eccrine glands; the histogenetic association is based primarily on histochemical, immunochemical, or ultrastructural features. Nevertheless, eccrine carcinomas may be taxonomically segregated into 2 main groups, as follows: those that are histologically similar to certain benign appendage tumors (eg, sclerosing sweat duct carcinoma, porocarcinoma, malignant chondroid syringoma, malignant nodular hidradenoma, malignant eccrine spiradenoma) and those that show a diverse array of histologic features, not recapitulating to any degree aspects of a benign counterpart.

A slightly different method of eccrine carcinoma classification is suggested by Galadari et al,1 who divide these tumors into those that arise de novo in normal skin and those that originate within preexisting benign sweat gland tumors. Precise identification based on histology is of significant importance because therapy and prognosis vary according to microscopic appearance (see Histologic Findings).

Pathophysiology

Eccrine carcinoma may be derived de novo from any portion of the normal eccrine apparatus or result from the transformation of an existing benign eccrine tumor.

A 2000 study by Takata et al2 examining the incidence of cytogenetic abnormalities in malignant eccrine tumors showed low incidences of loss of heterozygosity (LOH) or TP53 alterations in a mixed group of these neoplasms, in contrast to the frequent and multiple genetic abnormalities seen in tumors arising from epidermal keratinocytes. The authors speculate that this difference may be partly explained by the fact that the bulk of a sweat gland lies deep in the dermis where it is relatively protected from the sun and environmental mutagens. The precise role of ultraviolet radiation (UVR) remains to be elucidated, as another study analyzing TP53 mutations in 16 sweat gland carcinomas identified 3 G:C ® A:T transitions at dipyrimidine sequences on the antisense strand.3

Abbate et al4 suggest that genetics may play a role in the development of microcystic adnexal carcinoma (MAC).

Frequency

United States

Primary eccrine carcinomas are exceedingly rare, accounting for roughly 1 of 13,000 specimens submitted to a dermatopathology laboratory. The more common subtypes include microcystic adnexal carcinoma, eccrine porocarcinoma, and hidradenocarcinoma. The less common subtypes include eccrine mucinous carcinoma, malignant eccrine spiradenoma, malignant mixed tumor, malignant cylindroma, and papillary eccrine adenoma.

International

Only several hundred cases of eccrine carcinoma have been reported in the literature worldwide. No specific data are available regarding United States versus international incidence of eccrine carcinoma.

Mortality/Morbidity

Data regarding precise figures for eccrine carcinoma are insufficient; however, many of these tumors metastasize (up to 60%), with a fatal outcome.

Race

MAC was previously only described in white patients; however, Peterson et al5 and Gardner et al6 report the first and second cases of MAC affecting African Americans, respectively.

Sex

Sex incidence would appear to be equal for eccrine carcinoma, although this has not been definitively stated. Exceptions to this are the malignant chondroid syringoma and primary cutaneous adenoid cystic eccrine carcinoma, both of which occur more commonly in females than in males.

Age

Eccrine carcinomas most commonly are diagnosed in patients in their fifth through eighth decades of life.

Clinical

History

  • Malignant eccrine tumors generally present as a single, asymptomatic, nondescript cutaneous lesion.
  • Eccrine carcinomas grow either slowly over years or rapidly, reaching a size of several centimeters over a few months.
  • With disseminated disease, patients may report symptoms related to organ specific metastases.

Physical

  • Cutaneous/primary lesion of eccrine carcinoma 
    • A solitary nodule or plaque on the head or extremities and, less commonly, the trunk is present.
    • Occasionally, the lesion may ulcerate.
    • A few tumor subtypes do exhibit salient clinical features. 
      • MAC occurs as an indurated plaque especially in the nasolabial area.
      • Mucinous eccrine carcinoma predominantly involves the eyelids and has also been described on the scalp.7,8
      • Aggressive digital papillary adenoma/adenocarcinoma typically is seen in males on the digits and adjacent skin.
      • Most hidradenocarcinomas occur on the head and neck of older patients.
      • Most eccrine porocarcinomas are found on the lower extremities of older adults.
  • Disseminated eccrine carcinoma disease 
    • Nodal and distant metastases may be detected.
    • In particular, eccrine porocarcinoma (the most common eccrine cancer subtype) shows a characteristic propensity to produce multiple cutaneous metastatic deposits concomitant with visceral spread.

Causes

An etiologic role for UVR has been suggested for eccrine carcinoma. A case of MAC was reported in the neck of a man who received radiation therapy to the site years earlier. In addition, Abbate et al4 report that 5 out of 10 patients with MAC gave a prior history of radiation therapy. Chiller et al9 report a potential etiologic role for UVR as they describe MAC predominantly affecting the left side of the face, corresponding to higher UVR exposures while driving.

Immunosuppression has been known to increase the risk of nonmelanoma skin cancers, particularly squamous cell carcinomas. In a 2003 retrospective review of appendageal tumors in organ transplant recipients, Harwood et al10 suggest that patients who are immunosuppressed have a propensity to also develop cutaneous appendageal tumors over their immunocompetent counterparts, with increased rates of both benign eccrine tumors and malignant eccrine tumors.
