Secondary hip-buttock-thigh plasty.

Correction of sequelae of primary hip-buttock-thigh plasty has become a common challenge in aesthetic plastic surgery. Suggested techniques for dealing with this problem include denuding the skin at the depressed area, pulling thigh flaps upward and outward, using dermal buried flaps, and utilizing liposuction. Liposuction can be used successfully in combination with classic hip-buttock-thigh plasty to enhance the aesthetic result as well as to facilitate the surgical technique.

Secondary thigh-buttock deformities after classical techniques. Prevention and treatment.

Secondary high-buttock corrections pose difficult problems because of the poor vascularization of certain areas, the limited mobilization of the soft tissue, and the tendency toward poor scar formation. These factors limit the surgical techniques available. The tendency for the deformity to recur may necessitate several corrective procedures. The authors discuss correction of supratrochanteric depressions, trochanteric bulges, scars, contour irregularities, perineal bands, and flat buttocks.

Hemipelvectomy for buttock tumors utilizing an anterior myocutaneous flap of quadriceps femoris muscle.

Hemipelvectomy utilizing an anterior myocutaneous flap is indicated for aggressive tumors of the buttock and proximal portion of the posterior thigh. A large operative defect created posteriorly by amputation of the lower extremity, hemipelvis, and buttock is covered by a myocutaneous flap of quadriceps femoris muscle and overlying skin and subcutaneous tissue. The superficial femoral artery is preserved to sustain the myocutaneous flap.

Pulsatile buttock mass: report of two cases and a review of the literature.

The presence of any pulsatile mass suggests an underlying aneurysm. When such masses occur in the buttock, the differential diagnosis includes aneurysms arising from branches of gluteal vessels or aneurysms developing in a persistent sciatic artery (PSA). The investigation and management of two patients with pulsatile masses are described. Review of the embryologic aspects of these masses and the important literature on the subject led to the conclusions that when a pulsatile buttock mass is encountered, an anomalous PSA should be suspected. A gluteal artery aneurysm can be treated by ligation or occlusion, but for a sciatic artery aneurysm surgical ablation is necessary and distal perfusion must be achieved postoperatively.

Three-dimensional computer model of the human buttocks, in vivo.

In an effort to reduce the incidence of decubitus ulcers among wheelchair users, current work in cushion design concentrates on minimizing the pressure at the buttock-cushion interface. Finite element analysis can show the stress levels throughout the soft tissue between the cushion and the ischial tuberosity and give designers a better indication of the effects of a particular cushion. Finite element models were generated of the tissues around the ischial tuberosities of male and female subjects. Linear three-dimensional models were generated using a 386 computer and solved with infinitesimal deflection theory. The resulting minimal principal stresses were 17 kPa and 15 kPa at the buttock-cushion interface for seated male and female subjects, respectively. Computational results were verified experimentally with magnetic resonance imaging and interface pressure measurements.

[Diagnostic difficulties with a tumor in deep tissues of the buttock].

Diagnostic difficulties in a case of a large tumor localized in the deep tissue of buttock in a 29-year old woman is described. The patient was very severely ill presenting with neurological symptoms and immobilization of the left coxal joint, what strongly suggested a neoplasm and this was supported by the CT scan. USG examination allowed diagnosis of a deep hematogenic staphylococcal abscess of the buttock, probably due to extensive oral sepsis and staphylococcal septicaemia. Systemic antibiotic therapy as well as evacuation of pus caused a complete recovery of the patient.

Bilateral beta 2-microglobulin amyloidomas of the buttocks in a long-term hemodialysis patient.

Only two cases of beta 2-microglobulin amyloid tumors involving the buttocks have been reported in the world literature. We report a case of bilateral buttock amyloid tumors with associated carpal tunnel syndrome and pathologic fracture involving the femoral head. This unusual local bilateral manifestation of the beta 2-microglobulin amyloidosis develops late in the course of hemodialysis and may be initiated by chronic trauma.

The role of sigmoidoscopy in the management of gunshot wounds to the buttocks.

The charts of all patients (n = 70) admitted over 26 months after sustaining a gunshot wound to the buttocks were reviewed to assess the role of physical examination, routine radiologic studies, and sigmoidoscopy in the evaluation of these patients. There were 68 men and 2 women. Sixteen patients underwent sigmoidoscopy, which demonstrated a rectal injury in 7. Six of these patients had other abnormalities on either physical examination or plain pelvic radiographs that would have otherwise led to operation. There were no missed injuries and no morbidity in the remaining patients that were managed without sigmoidoscopy. Indications for sigmoidoscopy were gross blood on rectal examination in 2, bullet path with proximity to the rectum in 13, and persistent abdominal pain in 1. All patients with gross blood on rectal examination (n = 5) and blood at the urethral meatus (n = 2) had visceral injuries. One patient underwent celiotomy for an injury at 15 cm that was noted on sigmoidoscopy performed because the bullet trajectory was in proximity to the rectum. Sigmoidoscopy can be performed selectively in patients sustaining a gunshot wound to the buttocks when the proximity of the wound to the rectum is in doubt.

Primary cutaneous melanoma of the buttock: does injury from ultraviolet light play a role?

A 38-year-old man, initially referred for Mohs' surgery of a facial skin cancer, was found to have a thin (less than 0.5 mm thick, Clark Level II) primary cutaneous melanoma of the buttock. The melanoma, previously unnoticed by the patient, was 0.5 cm in diameter. Sunburn, a widely recognized risk factor for primary cutaneous melanoma, had occurred on the patient's buttocks during skinny dipping 20 years earlier. Traumatic injury due to ultraviolet light exposure may explain the subsequent development of some skin cancer on sites ordinarily protected by clothing.

Malignant peripheral nerve sheath tumors of the buttock and lower extremity. A study of 43 cases.

Using strict clinical and pathologic criteria for the inclusion of cases, the authors have reviewed the clinicopathologic features of 43 malignant peripheral nerve sheath tumors of the buttock and extremity seen over a 35-year period. Twenty-three (53%) of the patients had neurofibromatosis (VRN), whereas 20 (47%) did not. Fifty-one percent of the patients were women. The mean age at presentation was 36 years for patients with VRN and 44 years for patients without VRN. A nerve of origin was identified for 72% of the cases and an associated neurofibroma for 44% (65% with VRN and 20% without VRN). The mean greatest dimension of the tumors was 12.3 cm, and this did not differ significantly between the two groups. The predominant histologic pattern in 86% of the tumors was that of tightly packed spindle cells in an interlacing and woven pattern; heterologous sarcomatous elements were noticed in 12% of the cases. Surgical resection was the main modality of treatment for all patients; 65% also received adjuvant therapy. Follow-up evaluation was done in every case. An unexpected finding was the absence of a significant difference in survival rates between patients with and without VRN. Overall, 63% of the patients died of tumor: 65% of the patients with VRN and 60% of the patients without VRN. Large tumor size and high mitotic rate (greater than 20 per 10 high-power fields) portended a poor prognosis, as did the need for resection by amputation. Adjuvant radiation therapy and chemotherapy did not affect survival rates.

Sarcoma of the buttock: a trend toward limb-saving resection.

A retrospective comparison was made between soft tissue sarcomas of the buttock treated during two consecutive periods at one institution: (1) 1966-1978, during which almost all tumors were treated by radical buttectomy with limb preservation, often in conjunction with radiation therapy, and (2) 1934-1966, as previously reported by Wanebo et al, in which treatment by hemipelvectomy was frequently offered. Desmoid tumors were excluded. The five-year survival rates after curative treatment were almost identical, 40% vs 39%, respectively. Distant metastases were the main cause of death. Very high local recurrence rates were recorded after therapy: 45% vs 39% for the respective periods. Local recurrences seemed prone to occur with large, deeply fixed sarcomas, particularly when inadequate or no radiation therapy had been utilized. These observations point to the need for innovative methods to prevent local tumor recurrence and a trial of adjuvant chemotherapy if long-term cure with limb preservation is to be achieved.

Gangrene of the buttock: a devastating complication of the infusion of hyperosmolar solutions in the umbilical artery at birth.

This paper describes two cases of gangrene in the buttock secondary to infusion of a hyperosmolar solution into the umbilical artery at birth. Because of the frequent dilatation of the umbilical arteries in asphyxiated infants, needle puncture should not be used to infuse fluids into the umbilical vein. Moreover, hypertonic solutions that can produce vascular thrombosis should be avoided in metabolic resuscitation in the delivery room.

Rectal duplication in an adult: unusual cause of a buttock mass. Report of a case.

PURPOSE: Duplications of the rectum are extremely rare embryologic events, with almost 70 cases reported in the world literature. We report on a 39-year-old female patient with a duplication of the rectum. METHODS: Physical examination showed a left buttock mass; rectal examination revealed the presence of a painless mass compressing the rectum posterolaterally, confirmed by computerized tomography. RESULTS: The patient was operated on with a abdominal then a sacrococcygeal approach. After a complete excision, the postoperative course was unremarkable. Histology revealed a rectal duplication lined with heterotopic cylindric ciliated epithelium. DISCUSSION: This case shows that the diagnosis of rectal duplication is difficult and can be confused with other types of anorectal pathology. The presence of heterotopic ciliated epithelium has rarely been described. Complete excision of the duplication should be possible in most cases using a transcoccygeal, transanal, or abdominoperineal approach, depending on anatomic considerations.

Fat grafting of the buttocks and lower limbs.

This article presents the senior author's experience in fat grafting for the treatment of contour deformities of the buttocks and lower limbs. This method has been termed liposculpture and consists in removal of adipose tissue by cannula and syringe and cleaning of the aspirated material with saline. All external contact is thus carefully avoided, preventing contamination. Fat grafting is done in multiple tunnels in a deep plane. Total of 140 patients were treated over the last 5 years and results were considered uniformly satisfactory. Fat absorption was estimated by clinical evaluation to be less than 20% volume. A low rate of complications (less than 3%) supports the authors' opinion that this is an efficient and safe procedure to correct or enhance contour deformities of the lower limbs.

Isolated metachronous metastases to soft tissues of the buttock from a colonic adenocarcinoma.

The more common patterns of dissemination and recurrence of colonic cancer are known and well-documented. In contrast, extravisceral, distant soft tissue metastases are comparatively rare. Therefore, these metastases are not subject to meaningful generalizations, with the exception that they are often associated with widespread metastatic disease. This report describes the first case of carcinoma of the colon metastatic to the skeletal muscle of the contralateral buttock and the sciatic nerve without concurrent evidence of pelvic or distant metastases. Curative resection was not possible because of involvement of the proximal sciatic nerve.

Transluminal angioplasty of the hypogastric artery for treatment of buttock claudication.

Two patients with incapacitating isolated buttock claudication and bilateral hypogastric artery occlusive disease were treated by balloon dilatation of a single hypogastric artery. Symptoms were eliminated in 1 patient and reduced in the other. Percutaneous transluminal angioplasty represents an effective therapeutic approach in this relatively uncommon situation.

Fibroid in the buttock: an unexpected diagnosis.

Uterine leiomyomas (fibroids) are very common lesions with well-described imaging features. We present an unusual case of a fibroid which presented in the buttock with atypical clinical and imaging features in a woman who had had a previous hysterectomy. Despite extensive imaging and biopsies, the diagnosis was not suspected until pathological evaluation of the resected mass. The differential diagnosis for such a lesion, and the imaging and pathological features of fibroids, including atypical and parasitic leiomyomas, are discussed.
