DISCLAIMER
In general 70% of sSMC carriers are clinically normal. The figures listed above

are based on the bias, that mainly clinically aberrant cases are studied and reported in literature!

dysmorphic features; pregnancy and delivery at term were normal. Birth weight was 2200g, length 45cm and head circumference 32cm. At birth: prominent hairy forehead with hair extending up to the cheeks, upslanting palpebral fissures, depressed nasal bridge with short nose and very smooth philtrum, thin upper lip which was turning downward, low set ears, micrognathia , chubby cheeks, contracture of the fingers with postaxial polydactyly of left hand, widely separated toes which were overlapping, streaky pigmentation on the inner aspect of both fore arms distributed along the lines of Blaschko. Ophthalmological exam was normal. Echocardiography showed sub-aortic ventricular septal defect (VSD), pulmonary hypertension and moderate valvular pulmonary stenosis. Skeletal survey showed a tiny projection of the tip of coccyx, a tail-like sacrococcygeal appendage. Computed tomography scan of the lumbosacral spine showed prominence of coccyx and outward projection. Magnetic resonance imaging of the brain showed partial hypoplasia of the corpus callosum and slight hypoplasia of the cerebellum.

Born by vaginal delivery at 36 weeks of gestation; birth weight 2,905 g (25th centile); Prenatal ultrasound had shown a megaureter and an enlarged kidney on the right side. At 4 weeks, his growth parameters were all at the 25th centile. The skin showed streaky hyperpigmentation with whorl-like and streaky patterns that were most pronounced over the trunk and extremities; wide open anterior and open posterior fontanel, ocular hypertelorism, upslanting eyes, depressed nasal bridge, and a preauricular pit on the right side. Accessory nipples were present bilaterally. Testicles were undescended. His hands showed bilateral miniature postaxial polydactyly, clinodactyly of the 5th fingers with only one flexion crease, mild flexion contractures of the metacarpophalangeal joints of other fingers, and bilateral transverse palmar creases. Rocker bottom feet and eversion of the right foot were present. At age 6 weeks, he developed tonicclonic seizures; left cerebral ventricle that was slightly bigger than the right by computed tomography scan; right pulmonary artery stenosis; duplication of the right kidney with hydronephrosis and a normal left kidney; slight nystagmus; psychomotor delayed; mild delay in all areas of development.

A 50-year-old man presented with a history of cough, hemoptysis, and thoracic pain (regular smoker); cavitating tumor of the right upper lobe diagnosed ( T2 N0 M0). right upper lobectomy showed an excavated tumor 6x5x3 cm. The tumor cells positive for cytokeratin 7, not for cytokeratin 20. Sarcomatoid carcinoma of the lung of the pleomorphic carcinoma subtype was diagnosed. One month after surgery, the patient developed a subcutaneous metastasis on the right thigh (M1). Chemotherapy with cisplatin (100 mg/m2 on day 1) and vinorelbine (25 mg/m2 on days 1, 8, 15, and 22 of a 28-day cycle), but after three cycles the patient progressed with the development of multiple subcutaneous metastases. One of the abdominal wall metastases (M2) was resected for palliative intent 8 months after the initial diagnosis. After two additional lines of chemotherapy, the patient died of progressive disease 13 months after the initial diagnosis.
