ABSTRACT
Introducción: Los lipomas son los tumores subcutáneos de tejido blando más comunes, con una incidencia de 1 por cada 1.000 personas. Se presentan generalmente entre los 40 y 60 años de edad. El objetivo de este trabajo fue realizar una caracterización epidemiológica de los lipomas subcutáneos. Metodología: Se realizó una búsqueda computacional sobre la base de datos del Servicio de Cirugía del Hospital Dipreca para localizar los pacientes operados con diagnóstico clínico de lipoma y luego se revisó el informe diferido de Anatomía Patológica. Resultados: La muestra estuvo conducida a 110 pacientes, correspondiendo 52% a sexo femenino. La edad de la muestra se concentró en un 65% entre los 40 y los 69 años. El 54% de los lipomas se localizaron en el tronco; de éstos destaca un 62% de localización en dorso, siendo la localización inguinal la menos frecuente. La biopsia diferida correspondió en un 72% de los casos a lipoma.
Introduction: Lipomas are the most common subcutaneous tumors of tender tissue, with an incidence of 1 in 1000 people. The greater incidence is between the ages of 40 and 60. The objective of this trial is to establish an epidemiologic description of subcutaneous lipomas. Methodology: A computational search of the Dipreca Hospital Surgery Department data base was carried out in order to locate patients diagnosed with lipomas that underwent surgery, and the correlation with pathology exams was reviewed. Results: 110 patients were studied, 52% women. 65% were between the ages of 40 and 69. 54% of the lipomas were located in the trunk, of which 62% were located in the back, being the groin the less affected area. Histopathology exams were conclusive of lipoma in 72% of cases.

PURPOSE: Hibernoma is a very rare benign soft tissue tumor of the hypervascularized brown fat tissue with no malignant potential. MATERIALS AND METHODS: However, it is difficult to differentiate a hibernoma from other malignant tumors, such as liposarcoma using computed tomography and magnetic resonance imaging, and a surgical resection with histological confirmation is the treatment of choice. RESULTS: Histopathologically, hibernoma is composed of brown adipose cells that are polygonal and multivacuolated with a centrally located nucleus and granular cytoplasm, unlike white adipose cells. CONCLUSION: This article describes a patient with a histologically-confirmed hibernoma of the right shoulder.

A chondrolipoma is an extremely rare form of a benign mesenchymal tumor containing mature cartilage and fatty tissue. Chondrolipomas may be found in almost any part of the body, particularly in the connective tissue of the breast, head and neck area, as well as in the skeletal muscle. However, to the best of our knowledge, chondrolipomas located in the pelvic cavity have not been reported. In this case report, we describe a case of a chondrolipoma in the pelvis, and show that it has its own characteristic imaging findings, which included the composition of fatty tissue and calcification in most parts, as well as some focal areas of chondroid tissue based on the CT and MR findings.
