Deterrence/Prevention
- Sun protection would be prudent to the extent that UVR is considered a potential causative factor in eccrine carcinoma; however, this is only speculative at this point.
Complications
- Eccrine carcinomas may cause complications secondary to local invasion or metastatic disease.
Prognosis
- After studying a group of 35 patients with a limited variety of eccrine carcinoma subtypes, Mehregan et al[17] concluded that while all have a tendency for local recurrence, local lymphatic spread or distant metastasis occurs in less than 10% of cases. Indeed, the precise behavior of a given tumor seems to correlate well with its histologic subtype. While the prognosis for disseminated disease is believed to be grim, insufficient experience exists to allow tabulation of specific survival data.
- Sclerosing sweat duct carcinoma and primary cutaneous adenoid cystic carcinoma have been implicated in local recurrences only.[18]
- Eccrine adenocarcinoma, malignant chondroid syringoma, and malignant nodular hidradenoma are particularly prone to metastasize.[19]
- Porocarcinoma also may metastasize widely.
- Malignant eccrine spiradenoma reportedly spreads to regional lymph nodes and systemically, but too few cases have been described to enable a generalized statement regarding the behavior of this tumor.
- Mucinous eccrine carcinoma occasionally spreads to regional nodes but only rarely metastasizes.
- Aggressive digital papillary tumors are locally destructive but also metastasize not infrequently (14% in one study).[20]
