ABSTRACT
Solid-cystic hidradenoma is a benign cutaneous tumor with eccrine sweat gland origins that is most commonly found in the head, neck, trunk, and upper extremity regions of patients in the middle to older age groups. These lesions are generally asymptomatic, slow-growing, solitary, and nonulcerative in presentation. Degenerative malignant transformation of this tumor is very rare. In this case report, the authors describe the marginal surgical excision and subsequent microscopic pathologic diagnosis of a moderate sized solid-cystic hidradenoma of the dorsolateral forefoot in a middle-aged male patient.

A glomus tumor is an uncommon, predominantly benign, neoplastic lesion that primarily involves a thermoregulatory microvascular apparatus, the glomus body. Although these lesions can occur anywhere in the body, the subungual tissue of the hand represents the most common presentation site. Glomus tumors are not often encountered in the foot. Symptoms traditionally include the classic triad of pain, pressure, and cold sensitivity. This case report describes a variant location for a glomus tumor in the subcuticular tissue adjacent to the medial middle phalanx of the second toe. The nonsubungual location for this presentation should prompt the inclusion of glomus tumor in a digital soft-tissue lesion differential diagnosis. The lesion was excised surgically and was subsequently diagnosed histopathologically as a glomus tumor.

Angioleiomyomas are benign tumefactions that originate from smooth muscle in vascular structures and are difficult to definitively diagnose preoperatively. Although these lesions are rarely encountered in the foot, the lower extremity is the most common site of occurrence. An angioleiomyoma typically manifests as a small, painful, solitary, mobile lesion. This case report describes a lateral retromalleolar para-Achilles tendon insertional location for a moderately sized immobile solid tumefaction in the subcutaneous tissues. The lesion was nonpainful and progressively enlarged over 5 years. An excisional biopsy was performed, and the nodular lesion was subsequently diagnosed histopathologically as an angioleiomyoma. Owing to the ambiguous nature of the clinical findings, angioleiomyoma should be included in the differential diagnosis of lower-extremity soft-tissue manifestations.
