UNLABELLED Mammary hamartoma is an uncommon benign lesion. The frequency of the tumor is reported between 0.04 -1.15% and it accounts for 4.8% of all benign breast tumors. The lesion may be under-diagnosed by the clinician because of the varied clinical presentation or by the pathologist, as the microscopic appearance is not distinctive. A case of left sided mammary hamartoma in a 46-year-old f...

During the normal development of skin, pluripotential cells give rise to keratinocytes, sebaceus glands, hair follicles, apocrine glands and eccrine glands. A hamartoma, or an abnormal mixture of a tissue’s normal components, results from an error in development, among which some show malignant potential. We report two Chinese cases of giant congenital cutaneous hamartoma, a nevus sebaceus of J...

Apocrine nevus is a rare benign tumor of which only 9 cases have been reported in the literature. The apocrine nevus is seen mostly in the areas where the apocrine glands are normally distributed such as axillae, head and neck. Our case was a 16-year old girl who referred with a verrucous erythematous plaque over right parietal side of the scalp. The patient had the plaque since birth with part...

Breast hamartomas are rare, benign, tumor-like nodules composed of glandular, adipose and fibrous tissue. The hamartoma was first described in 1971 as a lipofibroadenoma, fibroadenolipoma or adenolipoma, based on the predominant component of the breast tissue. Clinical findings resemble fibroadenoma and if there is a palpable mass, the patients may receive an immediate diagnosis. Ductal hyperpl...

AIMS To review 25 cases of breast hamartoma and discuss the pathological criteria, and the usefulness of imaging modalities, fine needle aspiration cytology (FNAC), and needle core biopsy in the diagnosis. METHODS The hamartomas were assessed for interlobular fibrotic stroma, stromal adipose tissue content, pseudo-angiomatous stromal hyperplasia, and epithelial changes (hyperplasia, adenosis ...

Nevus sebaceus of Jadassohn is a congenital cutaneous hamartoma comprised of multiple skin structures. It has the potential to develop into variety of neoplasms of various epidermal adnexal origins. While multiple tumors may occasionally arise, it is unusual for more than four tumors to arise simultaneously within a single sebaceus nevus. Here in, we report a case of a 70-year-old woman with si...

Eyelid lesions are frequently seen in healthy infants. Common diagnoses include viral papilloma, chalazion, molluscum contagiosum, epithelial inclusion cyst, dermoid cyst, and capillary hemangioma. Less frequently recognized eyelid tumors consist of pilomatrixoma, apocrine hidrocystoma, pseudoepitheliomatous hyperplasia, neurofibroma, and choristoma. Characteristics of specific lesions, such as...

Syringocystadenoma papilliferum (SCAP) is a benign hamartomatous tumor arising from pluripotent cells with either apocrine or eccrine differentiation. We report a rare case of de novo linear SCAP in a 12-year-old female child with lesions over the chest along with the dermoscopic findings.

Tumours of cutaneous sweat glands are uncommon, with a wide histological spectrum, complex classification and many different terms often used to describe the same tumour. Furthermore, many eccrine/apocrine lesions coexist within hamartomas or within lesions with composite/mixed differentiation. In addition to the eccrine and apocrine glands, two other skin sweat glands have recently been descri...
