“…Thus, aggressive adenocarcinoma of the digit should be suspected clinically in a patient with a painful tumor of the digit. 87 This tumor is marked by dermal ductal and tubuloalveolar structures, which have papilla that project into cystlike openings. In addition, these papilla are lined by epithelial cells that project into smaller cystlike structures.…”

“…ADPA can be easily forgotten in the differential diagnosis and treatment is often delayed because of misdiagnosis, 3,4 as with our case. In light of previous reports, it is important to have a high clinical suspicion of ADPA when digital lesions such as soft tissue infections, cysts (ganglion, inclusion, mucous), calluses, pyogenic or foreign body granulomas, hemangiomas, osteomyelitis, gout, and cutaneous or subcutaneous tumors (adnexal tumors, squamous cell carcinomas, giant-cell tumors, or metastases of papillary adenocarcinoma originating in the colon, thyroid, or breast) present.…”

“…2 ADPA is often misdiagnosed, 3,4 which can delay the standard treatment of excision or amputation. In this study, we report a patient with ADPA that was initially considered to be a benign spiradenoma and was subsequently locally recurrent and progressed to metastatic disease.…”

“…The tumor originates within the dermis, but extension into the subcutaneous tissue may be present as well as epidermal involvement [2]. Tubuloalveolar and ductal architectural patterns as well as focal infiltration are commonly reported [2, 4, 7]. Variable cytologic atypia has been reported, but these and other histologic parameters have been shown to be poor predictors of metastatic potential in this tumor.…”

“…A variety of histochemical and immunohistochemical stains have been used to differentiate from metastatic adenocarcinoma and other tumors. Dermatologic entities with similarities in histologic appearance include hidradenoma, apocrine cystadenoma, eccrine acrospiroma, papillary eccrine adenoma, apocrine adenoma, chondroid syringoma, and tubular apocrine adenoma [2, 4, 7]. Specimens from these tumors may also be misdiagnosed as metastatic disease due to similarity in histologic architecture to adenocarcinoma of the breast, thyroid, and gastrointestinal tract [2].…”
