Calcaneal osteomyelitis can be a debilitating disease if proper treatment protocols are not initiated. This literature review details the epidemiology, clinical, diagnostic, and prognostic factors, and medical management in those who developed this disease.

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.

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.
