Myolipomas are very rare benign lipomatous soft tissue tumors which are usually located in retroperitoneum, abdominal and pelvic cavity, and the abdominal wall. They can be diagnosed histologically by the presence of irregularly admixed mature adipose tissue and smooth muscle fibers. The correct diagnosis of myolipoma is important, because it should be considered in the differential diagnosis of fat-containing lesions of the soft tissue and should follow a benign clinical course despite its frequently large size and deep location. We report here a case of myolipoma arising in the mesentery of the jejunum.

Prognostic Implications

Abstract Myelolipoma most commonly arises in the adrenal gland. Extra-adrenal myelolipomas are rare; to our knowledge, approximately 37 previous cases have been reported. We report a myelolipoma presenting as a localized mass in perirenal adipose tissue juxtaposed to the renal hilum in a 65-year-old Caucasian man who presented with back pain, weight loss, hematuria, and flank pain. The most likely diagnostic considerations were pyelonephritis or primary renal malignancy. However, histology revealed mainly mature adipose tissue along with multiple scattered islands of hematopoietic precursor cells. Representation of all the three hematopoietic cell lineages (granulocytic, erythroid, and megakaryocytic) was present. Perirenal masses such as morphologically identified myelolipomas are rarely, if ever, considered in differential diagnosis. The purpose of this report is to elicit consideration of extra-adrenal myelolipoma when formulating a differential diagnosis for perirenal and retroperitoneal tumors. Although primary and secondary malignant retroperitoneal tumors are much more common and aggressive neoplasms, establishing the correct diagnosis has important therapeutic and prognostic implications.

Neurogenic Tumors

Neurogenic tumors are an uncommon yet important category of soft tissue tumors in children and adolescents because of their frequent association with various genetic syndromes. The heterogeneous cellular composition of the peripheral nerve and the wide metaplastic capacity of the neural crest and its derivatives generate a variety of neoplasms with neurogenic differentiation. This article reviews the clinicopathologic features and differential diagnosis of neurogenic tumors in the first two decades of life, and highlights use of selected ancillary methods for diagnosis.

Extrarenal angiomyolipoma (AML) is an extremely uncommon lesion, accounting for less than 9% of all angiomyolipomas. We present a previously unreported case of a rarely located gigantic extrarenal angiomyolipoma at the posterolateral chest wall of a 35-year-old woman. Clinically, the lesion had all the characteristics of a benign tumor, being soft in palpation, painless, and growing in size in a slow rate. Histologically, the lesion consisted of convoluted thick-walled blood vessels without an elastic layer, interlacing fascicles of smooth muscle, and mature adipose tissue, features consistent with an angiomyolipoma. The mass was surgically removed, without any postoperative complications, and the patient has an uneventful postoperative course. Signs of local recurrence have not been observed. The purpose of this brief report is to point out the necessity of including angiomyolipoma in the differential diagnosis of adipose layer lesions.

The Right

Abstract Lipoblastomas are rare soft tissue tumors that predominantly affect the pediatric population. We describe a lipoblastoma of the right hand in a 16-month-old boy. Radiographically the tumor appeared large but fairly well circumscribed and composed primarily of fat. Pathologic evaluation revealed variably sized lobules of adipose tissue and myxoid immature mesenchymal tissue separated by prominent fibrous trabeculae. Cytogenetic analysis showed a clonal chromosomal rearrangement with a breakpoint involving chromosome 8q11.2, confirming the diagnosis of lipoblastoma and thus helping to expand the clinicopathologic spectrum of tumors in this diagnostic category.

Genetic Features

Many soft tissue tumors of childhood lack obvious differentiation toward a defined mesenchymal tissue type or have a phenotype that does not correspond to any defined normal tissue. These challenging tumors are currently regarded as neoplasms of uncertain differentiation. Nonetheless, there have been great strides in the understanding of their pathologic and genetic features and biologic underpinnings. The application of new genetic information to the pathologic diagnosis among this group of tumors is an emerging area in diagnostic pediatric pathology. This article reviews the clinicopathologic features of tumors of uncertain and/or miscellaneous origin, with an emphasis on the unique aspects of these neoplasms in children and adolescents, use of diagnostic adjuncts, and differential diagnosis.

Histological Variant

Lipomas are common benign soft tissue neoplasms derived from mature adipose tissue. However, they rarely arise in the oral cavity. Fibrolipoma is a histological variant of lipoma that mainly affects the buccal mucosa and causes functional and cosmetic issues. This article describes the case of a 71-year-old male with a fibrolipoma of the left buccal mucosa and a review of previous articles about fibrolipoma.
