ABSTRACT
Fibroadenolipoma is a solid, rare benign tumor. It is a circumscribed lesion composed of fat and other breast tissues which may be normal or which may show various changes. The reported incidence of breast hamartomas is 0.7% of all benign breast tumors in females [1]. Clinical findings resemble fibroadenoma and if there is a palpable mass, the patients may receive an immediate diagnosis. Ductal hyperplasia, apocrine metaplasia, calcification and adenosis may occur within the hamartoma, with rarer instances of lobular or ductal intraepithelial neoplasms.
ABSTRACT
Adenolipoma of the breast is an uncommon mammary lesion classified as a hamartomatous lesion, presenting as a soft, mobile and well-defined mass. The typical mammographic findings is of a wellcircumscribed lesion containing both fat and soft tissue surrounded by a capsule. Microscopically, adenolipoma exhibits a hamartomatous mixture of ducts and lobules intermingled with adipose and fibroconnective tissue. Enucleation is the standard treatment and recurrences are rare. We report a 29-year-old woman with a mobile, tender and firm mass, 6 x 5 cm, in the upper inner quadrant of the right breast of 1 month duration. Mediolateral mammography images demonstrated a welldefined mass with mixed granular and fat density. Histopathology of the excised mass revealed well-circumscribed lobules of ducts and glandular structures haphazardly embedded in mature fatty tissue. Breast hamartoma should be differentiated from other benign lesions of the breast. Awareness among radiologists and pathologists of this benign lesion would help avoid an incorrect diagnosis and unnecessary intervention.
ABSTRACT
Adenolipoma of the thyroid gland, also called thyrolipoma or thyroid hamartoma, is an extremely rare neoplasm. It is characterized by encapsulated admixtures of mature adipose tissue and thyroid tissue. The treatment of choice is surgical resection and the prognosis is favorable. We describe a case of adenolipoma of the thyroid gland, incidentally found in a residual gland subsequent to thyroidectomy of a papillary carcinoma.

Os adenolipomas tireoidianos são neoplasias raras e benignas, compostas de tecido adiposo maduro e folículos tireoidianos, de histogênese ainda indefinida, que acometem geralmente pacientes adultas do sexo feminino. Relata-se um caso de adenolipoma tireoidiano em paciente feminina de 65 anos de idade, discutindo-se os aspectos clínicos e laboratoriais e o diagnóstico diferencial.
Adenolipomas of the thyroid gland are rare and benign neoplasms composed of mature adipose tissue and thyroid follicles, with histogenesis still unknown. It commonly affects adult female patients. We report a case of adenolipoma of the thyroid gland in a 65 year-old female patient and discuss its clinical and laboratorial aspects and differential diagnosis.

Adenolipoma is a rare microscopic variant of a cutaneous lipoma with entrapped eccrine units or rarely, apocrineunits. Since the first description in 1993, only 34 cases have been documented. The most frequent site of origin was the thigh, followed by buttock and shoulder. To our knowledge, this is the first case report of adenolipoma on the sole of the foot in a 64 year-old female.

We report here a case of adenolipoma of the skin, an unusual variant of lipoma, arising on the neck. A 56-year-old man visited our hospital due to an anterior neck mass. An excisional biopsy was performed. The mass revealed a tan-yellow soft cut surface. We could not find any difference from other lipoma on gross inspection. Microscopically, the mass showed proliferation of mature adipocytes admixed with several eccrine units. The eccrine units were demonstrated by periodic acid-Schiff-positive granules in the secretory portions and by positivity of smooth muscle actin in the myoepithelial cells surrounding the eccrine glands. The tumor was completely excised, and the patient has been followed up without any evidence of recurrence so far.

Adenolipoma of the skin is an unusual variant of lipoma and this is characterized by the presence of normal eccrine sweat glands within a lipoma. This morphologically distinct variant is a rare lesion with a predilection for the thigh. We report here on a case of adenolipoma and we review the relevant medical literature.

Adenolipoma of the thyroid gland, also called thyrolipoma, is an extremely rare neoplasm characterized by encapsulated or tumorous mass of admixtures of mature adipose tissue and thyroid tissue. Only a few scattered cases have been reported in English literatures. It should be differentiated with encapsulated papillary carcinoma, follicular neoplasm and liposarcoma. We report an additional case of an adenolipoma of the thyroid gland.
