The Proteus syndrome is a congenital hamartomatous disorder delineated in 1983. Because of its polymorphic appearance, the syndrome was named after the greek god Proteus whose name means much less than the polymorphous much greater than. Major clinical findings include hemi hypertrophy, macrodactyly, exostoses, scoliosis, epidermal nevi, haemangiomas, deeply rugated soles of the feet and a variety of deep and subcutaneous masses. We report on 7 new cases of Proteus syndrome. All reported cases have been sporadic. Therefore this syndrome could be due to the action of a dominant lethal gene surviving by mosaicism.

The term Proteus syndrome was coined in 1983 to describe a disorder of skeletal, hamartomatous, and other mesodermal malformations. The syndrome was named after the Greek god Proteus, whose name means "the Polymorphous." Clinical features of this new syndrome are currently being defined. Including the case reported herein, we have found 34 patients with Proteus syndrome described in the English literature. Major clinical findings, defined as those findings seen in more than half of the cases, include hemihypertrophy, macrodactyly, exostoses, epidermal nevi, characteristic cerebriform masses involving the plantar or palmar surfaces, a variety of subcutaneous masses, and scoliosis. Histologic examination of subcutaneous masses has identified a variety of lipomatous, hamartomatous, and angiomatous tumors.

The Proteus syndrome (PS) and the Bannayan-Zonana syndrome (BZS) both have multiple hamartomata as prominent features. Hemihypertrophy, macrodactyly, exostoses, skin lesions, scoliosis, and sporadic occurrence are seen in PS, whereas patients with BZS have macrocephaly and related craniofacial findings. BZS has been observed in families as an autosomal dominant trait. Although the two syndromes can be distinguished in most patients, there are features in common to both that may pose a diagnostic dilemma in an isolated case. We report the case of a 3-year-old girl with macrocephaly, macrodactyly, and superficial and intra-abdominal hamartomata who illustrates the problem of differentiating between PS and BZS. We compare this patient and another recently reported patient with other published cases of PS and BZS. Patients with PS, in general, show more extensive systemic involvement, including skeletal and cutaneous manifestations. Macrocephaly, seen in all reported patients with BZS, is also found in 14% of patients with PS. Overlap among syndromes which include hamartomata as prominent features suggests that they might be etiologically or pathogenetically related. The present case also illustrates the usefulness of imaging techniques in the diagnosis of mixed mesodermal hamartomata.

We report on 11 new cases of Proteus syndrome to illustrate the broad range of the phenotype in this hamartomatous dysplasia. The cardinal manifestations of this sporadic disorder are hemihypertrophy, macrodactyly, exostoses, scoliosis, cavernous hemangiomas, lipomas, linear sebaceous nevi, and deeply rugated soles of the feet. Intelligence is usually normal. The differential diagnosis includes Klippel-Trenaunay-Weber and partial lipodystrophy syndromes.

A clinical entity called "the epidermal nevus syndrome" does not exist. Rather, there are various epidermal nevus syndromes that can be distinguished by clinical, histopathological, and genetic criteria. In this review, five distinct epidermal nevus syndromes, recognizable by different types of associated epithelial nevi, are described. The Schimmelpenning syndrome is characterized by a sebaceous nevus associated with cerebral anomalies, coloboma, and lipodermoid of the conjunctiva. By contrast, cataracts are a prominent feature of the nevus comedonicus syndrome. The pigmented hairy epidermal nevus syndrome includes Becker nevus, ipsilateral hypoplasia of the breast, and skeletal defects such as scoliosis. In the Proteus syndrome, the associated epidermal nevus is of a flat, velvety, nonorganoid type. The CHILD syndrome occurs almost exclusively in girls. The associated CHILD nevus shows unique features such as a diffuse form of lateralization, ptychotropism, and microscopic changes of verruciform xanthoma. The five epidermal nevus syndromes differ in their genetic basis. The Schimmelpenning and nevus comedonicus syndromes are most likely nonhereditary traits. By contrast, the pigmented hairy epidermal nevus syndrome and the Proteus syndrome may be explained by paradominant inheritance. The CHILD syndrome is caused by an X-linked dominant mutation exerting a lethal effect on male embryos. A correct diagnosis of these phenotypes is important for both recognition and treatment of associated anomalies as well as for genetic counseling.

We report on a case of an 11 year old girl with Proteus syndrome involving both kidneys morphologically and functionally. The patient had hemihypertrophy, scoliosis, overgrowth of lower extremities, partial macrodactyly, subcutaneous lipoma, and pigmented nevi compatible with the Proteus syndrome. She also had overgrowth of the right kidney with mildly impaired function and a small left kidney with severe dysfunction. Morphological involvement of visceral organs has previously been described; however, deteriorating renal function has not previously been reported in this syndrome.

A male patient followed from the age of 3 to 25 years was eventually diagnosed as having Proteus syndrome. He was born with linear epidermal nevi of the neck and forearm and presented with macrodactyly of the right hand and progressive hemihypertrophy of the right lower limb recurring after multiple reduction operations. The bone ends showed disorderly overgrowth of hyaline and fibrocartilage mixed with collagen and bone, and early differential diagnoses included Ollier's disease. The child also had vertebral anomalies, scoliosis, a bony protrusion of the cranial vertex, and strabismus. In the second decade he developed gyriform swelling of the soles, retinopathy, bilateral papillary cysts of the epididymis, and a giant cyst of the left kidney with complex glandular foci. At 22 years a 3-cm meningioma containing adipose tissue was resected, and at 24 years a 3-cm cellular nodule of the rete testis with hyperchromatic foci, probably an adenoma, was removed. The features of Proteus syndrome were those of hyperplasia and neoplasia of mostly mesodermal tissues. Unlike other reported cases, overgrowth of a finger recurred at 25 years.

We report the case of a 4-year old boy presenting with a polymalformative syndrome made of cutaneous and subcutaneous lesions associated with visceral and skeletal lesions. The cutaneous lesions consisted of 3 verrucous hamartomas, one haemangioma and one lymphangioma. The subcutaneous lesions were melting of panniculus adiposus, plantar tumefaction and diffuse lipomatosis of the peritoneal and retroperitoneal cavities. The skeletal lesions were uneven lower limbs and dorsal scoliosis. Atrophy of the intestinal villi was also found. The diagnosis of Proteus syndrome was made.

A case of Proteus syndrome in a 13-year-old boy with macrodactyly, hemihypertrophy, exostosis of the skull, epidermal naevi, palmar and plantar masses, and scoliosis is reported. Macrodactyly involving the left thumb was treated surgically. The usual findings in macrodactyly, hypertrophy of the digital nerves and proliferation of subcutaneous fat, were not observed in this case. Macrodactyly associated with Proteus syndrome should be distinguished from other forms of macrodactyly because of its poor prognosis and high rate of recurrence.

Tracheomalacia is a condition characterized by weakness of the tracheal walls and supporting cartilage. It may be congenital, occurring in association with other lesions, such as vascular ring, tracheoesophageal fistula, dyschondroplasia, congenital cysts or tumors, or it may be acquired, most commonly as a result of protracted endotracheal intubation and less often of irradiation, trauma or neoplasm. We present a case of acquired tracheomalacia in a 15-year-old boy, a victim of Proteus syndrome (hemihypertrophy, subcutaneous tumors, and macrodactyly), who had congenital scoliosis with secondary chronic restrictive pulmonary disease, for which he was admitted to our hospital for surgical correction of the spine. Unfortunately, his conditions, particularly of respiratory, worsened after the operation, which called for an emergent tracheostomy. During the procedure, high airway pressure and CO2 retention developed, and an extreme narrowing of the tracheal lumen was revealed by fiberoptic bronchoscopy. Acquired tracheomalacia was diagnosed. The probable mechanisms, diagnostic tests, and treatments of tracheomalacia are hereunder discussed.
