BACKGROUND Tubular papillary adenoma is a rare eccrine-derivate dermal adnexal tumor, located in the scalp mostly. Earlier, the sebaceous cyst size was larger than 5 cm in diameter and may be confused with subcutaneous tumor. Cases of the tumor on the buttock with rapid growth are rare, therefore magnetic resonance imaging (MRI) may be helpful to determine their precise size, nature, and invasion of nearby organs for further confirmation. CASE REPORT We report on a case of a 35-year-old male with a rapid-growth tumor on the buttock. Initially, he had received drainage by syringe and the amount of drainage was 50 mL. MRI favored diagnosis of sebaceous cyst. As for recurrent tumor, the pathology revealed tubular papillary adenoma. CONCLUSIONS MRI might play an important role on imaging of soft tissue to exclude some uncertain malignant tumors. This case report indicated a rare case of a large rapid-growing tubular papillary adenoma on the buttock that required further management.

Cutaneous adnexal tumors include lesions with apocrine, eccrine, follicular, sebaceous, and mixed differentiation. Most are benign and sporadic, although malignant forms are occasionally observed and some cases develop in the setting of inherited syndromes. These tumors often cause immense diagnostic difficulty. Dermoscopy is a noninvasive technique that has greatly improved the diagnostic accuracy of different skin lesions, including these tumors. We provide a review of the literature on the dermoscopic structures and patterns associated with adnexal tumors. Most patterns associated with this kind of tumor are nonspecific and are observed in other nonadnexal tumors, especially in basal cell carcinomas.

Syringocystadenoma papilliferum is a benign adnexal neoplasm frequently seen in association with other adnexal tumours. We report the dermoscopic features of three cases of syringocystadenoma papilliferum developing in naevus sebaceus. Clinically the lesions were characterised by exophytic papillary structures. Dermoscopically, polymorphous vessels were the prevalent feature.
