A Rare Case of a Pedunculated Lipoma in the Perianal Region: A 20-Year Journey.

Lipomas are common benign soft tissue tumors, typically presenting as painless, slow-growing masses of mature adipose tissue. However, their occurrence as pedunculated lesions in the perianal region is rare. We present a case of a 70-year-old male with a 20-year history of a painless, cosmetically concerning mass in the perianal region. Clinical examination and ultrasonographic findings were consistent with a pedunculated lipoma. Surgical excision was performed successfully, and histopathological examination confirmed the diagnosis of lipofibroma. This case highlights the importance of considering unusual presentations of lipomas in the differential diagnosis of perianal masses. It emphasizes the role of surgical excision for symptomatic or cosmetically concerning lesions. Long-term follow-up is essential to monitor for recurrence and ensure optimal patient outcomes.

Which one is the most accurate naming convention: cutaneous lipofibroma or pedunculated lipofibroma?

This is a case of a large pedunculated lipofibroma on the left axilla in a 36-year-old woman. The lesion was excised completely with no recurrence after one year of follow-up. A new name for this rare entity is proposed to be more inclusive of all lesions of pedunculated lipofibroma and to differentiate it from another entity called fibrolipoma.

Necrosis of Pedunculated Lipofibroma by Nab-Paclitaxel.

We present a rare phenomenon of a soft tumor hanging on the woman's left upper arm that underwent necrosis from the distal aspect during chemotherapy for pancreatic cancer. The benign tumor, pedunculated lipofibroma, originally had normal color for 10 years and then became necrotic when she was treated with gemcitabine and nab-paclitaxel. Necrosis stopped in conjunction with chemotherapy cessation. Dermatologists must remember that nab-paclitaxel could develop necrosis of a skin tumor.

Lipofibromatous Hamartoma of the Median Nerve: A Case Report.

Lipofibromatous hamartoma (LFH) is a rare benign peripheral nerve tumor. The median nerve (MN) is most commonly affected in the upper extremity. We report a case of a 39-year-old male with LFH of the median nerve presented with swelling and symptoms of carpal tunnel syndrome treated successfully with decompression. LFH is reported with various descriptions because of the proliferative nature of its adipocytes and the fibrofatty infiltration within the peripheral nerves. Swelling around the volar aspect of the wrist remains the most frequent presentation of LFH. Surgical decompression without tumor resection can result in symptom improvement. In addition, post-decompression nerve coverage can be a solution to improve the residual hyperesthesia symptoms.

Lipofibromatous Hamartoma of the Median Nerve: A Case Report.

Lipofibromatous hamartoma is a rare and slow growing benign fibro-fatty tumor. It is characterized by the proliferation of mature adipocytes within the epineurium and the perineurium of the peripheral nerves. In the upper extremity, it most commonly affects the median nerve. Median nerve involvement commonly leads to pain, numbness, paresthesia and carpal tunnel syndrome. This article presents a case of lipofibromatous hamartoma in an 8-year-old child followed by a discussion of the epidemiology, diagnosis, imaging details and treatment options for this condition.

Heart-shaped pedunculated lipofibroma of the coccygeal area in a neonate.

Pedunculated lipofibroma is a rare benign hamartomatous condition that is characterized by ectopic adipose tissue in the dermis and a solitary form of nevus lipomatosus cutaneous superficialis. We describe here a neonate with congenital pedunculated lipofibroma. The lesion was removed by simple excision.

Nipple Shaped Solitary Nevus Lipomatosus Cutaneous Superficialis: Report of a Case and a Review of the Korean Literatures / 대한피부과학회지

Nevus lipomatosus cutaneous superficialis is a fairly uncommon form of connective tissue disorder, and this is characterized by the ectopic deposition of fat lobules in the dermis. There are two clinical variants: the multiple and solitary types. Particularly for the case of the solitary forms, it seems preferable to regard them instead as pedunculated lipofibromas. We report here on a case of a nipple shaped solitary nevus lipomatosus cutaneous superficialis, and we also review the Korean cases. Till now, 22 cases in Koreahave been reported as a solitary nevus lipomatosus cutaneous superficialis and a pedunculated lipofibroma, or both. The review of the Korean cases revealed that solitary nevus lipomatosus cutaneous superficialis almost always exhibits a single skin-colored dome shaped or pedunculated nodule on the thigh and buttock, as well as on the non-girdle area after the 4th decade, and it has no histopathological difference from the multiple forms.

Two Cases of Solitary Nevus Lipomatosus Superficialis (Pedunculated Lipofibroma) / 대한피부과학회지

Nevus lipomatosus superficialis is an uncommon form of connective tissue nevus and is manifest principally by the deposition of fatty tissue in the dermis. In this disease two clinical types are distinguished. The classic type consists of asymptomatic linear, soft, flesh-colored to yellowish papules or nodules that often coalesce into plaque. It is usually located in the pelvic girdle and lumbar area. The solitary form usually appears later in life and can occur at any site. Clinically, it may be confused with neurofibroma and acrochordon. The solitary form has been described as a pedunculated lipofibroma. There is no sexual predilection or hereditary trend. The authors experienced two cases of solitary nevus lipomatosus superficialis. The first case was a 57-year-old male who had a solitary, 1 cm-diametered, flesh-colored, polypoid nodule on the buttock for 4 years. The second case was a 32-year-old female who had a 1.5 cm-diametered, flesh-colored and light brown, polypoid nodule on the right flank for 10 years. Diagnosis was confirmed by clinical and histopathologic findings.

Two Cases of Pedunculated Lipofibroma / 대한피부과학회지

Pedunculated lipofibroma is a rare disorder characterized by ectopic deposits of mature adipose tissue in the dermis. It is a dorne shaped or sessile papule which occurs at any site and develops later in life. We, herein, report two cases of pedunculated lipofibroma which have developed on the chin of a 64-year-old man and the buttock of a 47-year-old woman.

Pedunculated Lipofibroma

A 45-year-old woman had a bean-sized, asymptomatic, soft nodule on the right buttock for 4 years. Histopafhologic evaluation revealed acanthosis and a central core of adipose tissue with thin papillary and reticular dermis containing eccrine glands. Staining with alcian blue showed a slight increase of mucopolysaccharides in the reticular dermis. We made the diagnosis of pedunculated lipofibroma as a solitary form of nevus lipomatosus superficialis.
