ABSTRACT
Lipomas are the most frequent soft tissue tumors. Osteolipomas are a rare variant that can be difficult to diagnose. We report the case of a 66-year-old man consulting with a tumor of 2 years development in the right paravertebral cervical region. Neurologically, the patient had no sign of myelopathy or neurological focality. Magnetic resonance imaging showed a mass with a lipid component and calcifications inside within the right paravertebral musculature with a possible origin in the right C3 posterior root. A computed tomography scan and guided biopsy were performed, revealing hematic material and small bone spicules with no apparent neoplastic element. The tumor was totally removed, including the right C3 posterior branch, and was confirmed to be an osteolipoma on biopsy. The patient remains asymptomatic at 6-month follow-up. The osteolipoma is a benign tumor of soft tissue, characterized by lipoma areas with mature bone tissue differentiation, and even with hematopoietic marrow.

Spindle cell lipoma, a rare variant of lipoma, is a benign tumor found in the posterior neck and shoulder. A 24-year-old man with a close family history of malignant lymphoma had presented with a large, firm, nodular mass found in the right supraclavicular area. Excision of the deeply located mass revealed a pale yellow, rubbery nodule which grossly resembled an enlarged lymph node, with a variant of lymphoma as a primary suspect. However, pathological studies revealed the lesion to be a spindle cell lipoma. Although atypical in location, spindle cell lipoma should always be kept in differential diagnosis of a newly-noted soft tissue mass, as this entity may be easily cured by simple excision.

Hibernoma is a very rare, benign soft fatty tumor that derived from remnants of fetal brown tissue. The following case of hibernoma break out occurred from a patient who had received surgical resection of neurilemmoma. There has never been a case that reported about hibernoma accompanied by neurilemmoma. It is anticipated that this experience would be helpful to other physicians who are interested in this rare type of tumor.

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.
