          Abstract

          Paratesticular tumors are rare and often benign causes of scrotal masses. Intrascrotal angiolipomas are an uncommon paratesticular tumor that has seldom been reported in the literature. This report describes a 77 year old man who presented with a 15 cm extratesticular mass. The mass was removed due to increasing discomfort and specimen pathology confirmed it as an angiolipoma. This case highlights the feasibility of conservative management for slow growing masses, such as angiolipomas.

          Posttraumatic lipoma: analysis of 10 cases and explanation of possible mechanisms.

          Nazan Sivrioglu, Eray Copcu (2003)
          Trauma and lipoma are the most frequently met occurrences in clinical routine. Although lipomas are well-known fatty tumors both clinically and pathologically, the precise etiology is still unknown. Generally, posttraumatic lipomas are known as "pseudolipoma," which describes herniation of deeper fat through Scarpa's layer secondary to trauma. Here we present 10 patients with lipoma secondary to blunt trauma in different anatomical sites. To correlate trauma and lipoma relationships and to discuss the possible pathogenetic mechanism by reviewing literature. Ten patients (12 lipomas) after blunt trauma were presented, and data of patients were reviewed. Ultrasonography and/or nuclear magnetic resonance were employed for diagnosis in addition to physical examination. All tumors were verified by histopathologic examinations. Patients were followed for a minimum of 6 months. The average age was 34. Four of the lesions (12 altogether) were located on an upper extremity, 5 on a lower extremity, 2 on the trunk, and 1 on the neck. Excision of tumors and primary closure were performed in 92% of the lesions, and only one liposuction was performed. Aesthetic results were achieved in all patients. There were no complications and recurrences. The effect of blunt trauma on fat tissue may be explained by different theories. We summarized possible mechanisms into two groups according to our observations and review of the literature: The first was related to mature adiposities and mainly a mechanical effect, and the second was differentiations of the preadipocytes to lipoma by the promoting factors. We speculate that only traumas that serve as a cause of fat necrosis may trigger the formation of the lipoma, and local inflammation secondary to fat necrosis may affect adipocytes and promote new formation of lipoma.

              Intranodal angiolipoma.

              Rasha Al-Otaibi, Abdulla H Darwish (2011)
              Angiolipomas are not uncommon tumors of the soft tissue, but are rarely found in other parts of the body. We report a case of intranodal angiolipoma in a 64-year-old man who presented with right inguinal swelling. Histopathological examination showed a tumor composed of mature adipose tissue and prominent vascular component, which is consistent with angiolipoma. We conclude that angiolipoma can be added to the list of conditions or diseases in the differential diagnosis of localized lymphadenopathy.
