INTRODUCTION: Kobberling-Dunnigan syndrome is characterized by a series of alterations in metabolism and body fat distribution. Body dysmorphism and the Cushingoid appearance may have negative social and psychological impacts on the patient, including difficulty with social adaptation. In such cases, liposuction is used with the aim of improving body contour, with consequent improvements in self-esteem. The results are long lasting when body weight is maintained.
CASE REPORT: Liposuction of the back, abdomen, and cervical regions in a woman with Kobberling-Dunnigan syndrome led to significant improvement in her body shape, and the results were maintained nine months postoperatively.
Keywords: Lipodystrophy. Lipectomy. Syndrome. Lamin type A/genetics.
INTRODUÇÃO: A síndrome de Kobberling-Dunnigan caracteriza-se por um conjunto de alterações metabólicas e de distribuição da gordura corporal. O dismorfismo corporal e o aspecto cushingoide trazem repercussões psicológicas e sociais, com dificuldade de ajuste social. Nesses casos, a lipoaspiração é empregada com o objetivo de melhorar o contorno corporal e, consecutivamente, as alterações de autoestima. Os resultados apresentam-se duradouros quando há manutenção do peso.
RELATO DO CASO: Paciente do sexo feminino, portadora de síndrome de Kobberling-Dunnigan, submetida a lipoaspiração de dorso, abdome e região cervical, com melhora significativa do contorno corporal e manutenção dos resultados nove meses após a operação.

Kobberling-Dunnigan syndrome is an autosomal dominant partial congenital lipodystrophy caused by mutations in the gene encoding a nuclear lamina protein, lamin A/C, which is associated with insulin resistance. Two forms of phenotypic manifestations have been described: type 1, in which there is loss of subcutaneous fat confined to the legs, face, and trunk, along with muscle hypertrophy and normal genitalia, and type 2, in which there is accumulation of fat in the entire trunk1-3.
The estimated prevalence of the Kobberling-Dunnigan syndrome is 1:15,000,000. This syndrome is observed only in females, according to genotypic studies conducted in five affected families (two Scottish and three German)1. This syndrome is thought to be of X-linked dominant inheritance and fatal in the homozygous form (XY)1,4. In the type 2 presentation, there is fat loss in the extremities and fat accumulation in the face, buttocks, abdomen, chest, groin, and axillary regions beginning during puberty, producing a Cushingoid appearance. There is also accumulation of fat in the viscera and muscles. The vulva is not affected, but there is hypertrophy of the vulvar outer lips1-3.
Insulin resistance arises before the clinical signs. A mutation in the nuclear lamin A/C gene leads to shortages of adipose tissue in the periphery, which affects peripheral resistance to insulin due to a deficiency in the removal of plasma fatty acids1. There is a decrease in glucose consumption in the periphery, hyperinsulinemia, hypoleptinemia, and decreased adiponectin2,4,5.
The Kobberling-Dunnigan syndrome is also associated with type IV dyslipidemia, which leads to reduction of high-density lipoprotein cholesterol (HDL-cholesterol) and severe hypertriglyceridemia. This may subsequently cause the appearance of xanthomas and acute pancreatitis2. Later, liver damage and acanthosis nigricans may occur1,4. In some cases, hirsutism, menstrual abnormalities, and polycystic ovaries develop without reproductive malfunction. A higher incidence of hypertension and acute coronary heart disease can also be observed4.
The prognosis of this syndrome is related to metabolic (diabetes mellitus and dyslipidemia) and cardiovascular complications. Body dysmorphism found in these patients is often accompanied by serious psychological disorders, with the development of depression and social isolation4. Liposuction can be recommended to improve body contour and help minimize the stigma associated with this syndrome.
The present study reports the case of a patient with type 2 Kobberling-Dunnigan syndrome in whom liposuction was performed for the treatment of body dysmorphism. The patient showed clinical improvement and maintenance of the results in the late postoperative period.
A 26-year-old female patient was referred by the Service of Endocrinology from Universidade Federal do Triangulo Mineiro, Uberaba, MG, Brazil, with a diagnosis of Cushing's syndrome. Since the age of 12 years, the patient had full-moon facies, which was accentuated at the age of 18 years. She also had Hashimoto's thyroiditis since the age of 8 years and primary hyperparathyroidism since the age of 22 years. She was surgically treated after two episodes of hypercalciuria and renal colic. Over the last three years, she has been afflicted with insulin-dependent diabetes, chronic urticaria, and severe dyslipidemia. She was also being treated with tegretol for depression over the last four years. Menarche occurred at the age of 12 years, followed by regular menstrual cycles; contraceptives had been used over the previous two years.
On physical examination, her body weight was 46.6 kg; height, 1.54 m; and body mass index (BMI), 19.6. She presented with bilateral proptosis, lagophthalmos, Cushingoid facies, complete filling of the supraclavicular fossa, slight dorsal gibbosity, and dry and atrophic skin with no purple streaks. She also had centripetal lipodystrophy of the face, abdomen, flanks, and genitalia with hypertrophy of the labia majora (Figures 1 to 3).
Liposuction under general anesthesia was recommended for the treatment of body lipodystrophy. She had significant visceral fat accumulation that hampered determination of abdominal wall thickness, even after carrying out preoperative computed tomography.
Liposuction was started in the areolar layer, progressing to the lamellar area. The skin redundancy between tweezers allowed for the best estimation of the position of the aponeurosis of the abdominal wall. An infiltration of 2,000 ml of saline with epinephrine (1:500,000) was administered, and a volume of 3,000 ml was aspirated from the abdomen, dorsal and cervical regions, and the labia majora.
The patient was discharged on the first postoperative day with a compression vest. She underwent manual lymph drainage after the first week.
There was improvement in body contour, with weight maintenance nine months postoperatively (Figures 4 to 6).
Congenital lipodystrophies are likely to cause serious psychological changes and increased morbidity. In type 2 Kobberling-Dunnigan syndrome, the changes begin at puberty, causing patients to feel less attractive and less feminine4. Periodic evaluations are necessary to maintain metabolic balance.
Liposuction is an important approach to normalize body contour and improve the patient's self-esteem1,4. In addition to the prevention of lipodystrophy reappearance, postoperative control of weight and diet may also prevent worsening of insulin resistance.
Liposuction may be used to successfully treat the lipodystrophy found in the Kobberling-Dunnigan syndrome. Lasting results depend on weight maintenance, which requires proper control of diet and frequent endocrine evaluations.
