“…The most acceptable etiology is that myelolipomas arise due to metaplasia of the reticuloendothelial cells of the blood capillaries in the adrenal gland in response to stimuli such as chronic stress, infection, necrosis, or inflammation [13]. Usually they are nonfunctioning and asymptomatic, however they can be found in association with obesity, hypertension and endocrine disturbances, such as Addison disease, Cushing syndrome and hyperaldosteronism, or they can co-exist with adrenal hyperplasia or functioning tumors [14]. Adrenal myelolipoma has been reported as occurring in the 5 th to 7 th decades of life.…”

Background: Myelolipoma is a benign and uncommon tumor of the adrenal gland. The majority is small and asymptomatic and is diagnosed incidentally. However it can be large and produce symptoms. The laparoscopic adrenalectomy is the gold standard for its treatment but can be challenging if the lesion is big because of technical aspects and the associated malignancy risk. Case Report: We present a case of an asymptomatic 37 years old man, with past history of arterial hypertension, that performed an abdominal ultrasound that showed a huge mass on the right adrenal gland with 98×85×96 mm, consistent with a myelolipoma. The abdomino-pelvic tomography confirmed the diagnosis and the functional study revealed a marginal elevation of plasmatic nor-adrenaline and catecholamines. The MIBG scintigraphy was normal. The lesion was removed by laparoscopy. Conclusion: The giant adrenal myelolipoma is a rare tumor. Laparoscopic adrenalectomy has become the gold standard in management of most adrenal masses. Even for giant adrenal masses, it can be done in a safe way, provided that is performed by an experienced laparoscopic team.

Background Myelolipoma is an uncommon benign tumor composed of mature adipose tissue and hematopoietic elements. These tumors generally affect the adrenal glands, with anomalous presentations being rare and with few cases described in the literature. Most myelolipomas are asymptomatic and discovered incidentally, either through imaging tests or at autopsies. However, depending on the location and size of the lesion, myelolipomas can cause symptoms of mass effect. This article aims to report a very rare presentation of a symptomatic primary myelolipoma affecting the ribs. Case presentation A 21-year-old white female patient presented with a complaint of burning chest pain over 3 months, with gradual worsening in intensity, accompanied by a progressively growing bulge in the right thoracic wall. The patient underwent thoracotomy of the fifth and sixth ribs with complete excision of the lesion with a safety margin. Thoracic wall reconstruction was performed using a polypropylene mesh. The patient had a good postoperative course and was discharged on postoperative day 3. Histopathological examination revealed a histological image consistent with myelolipoma. Conclusions This report underscores the importance of considering a myelolipoma diagnosis for tumor masses in the ribs.

Splenic myelolipoma in a dog

Myelolipoma is a benign neoplasm composed of mature adipocytes and hematopoietic elements. This tumor is rare in dogs and cats and can develop in several organs and tissues. This report describes a case of splenic myelolipoma in a dog characterizing its clinical-pathological and ultrasonography aspects. A 9-year-old, female, mixed-breed, castrated dog was referred to the veterinary hospital with increased abdominal circumference. Ultrasonography revealed splenomegaly with masses of not measurable dimensions along the entire length of the parenchyma. The spleen was removed, and a fragment was sent for histopathological analysis. Macroscopically, the spleen was enlarged, with irregularly nodular growths that project above the surface of the organ. Nodules were red with small yellow areas. Microscopically, the spleen was effaced by a well-demarcated and not encapsulated mass composed of histologically well-differentiated neoplastic adipose tissue with islands and nests of varying proportions of hematopoietic elements. Histological examination confirmed the diagnosis of myelolipoma. Myelolipomas are observed on ultrasound images as hyperechoic masses or nodules with homogeneous echo texture. Here, ultrasound appearance involved mixed echogenicity and heterogeneous echotexture, due to the mixture of fat and non-fatty material components of the tumor.
