Geographic Tongue

October 01, 2007

The sharply demarcated, smooth red plaques on this 3-year-old's tongue had been present for several months. The child initially refused to stick out his tongue. He cooperated after he was offered a lollipop (with the stipulation that "the wider he opened his mouth, the bigger the lollipop he would receive").

Gianotti-Crosti Syndrome

June 01, 2007

For about a week, a 4-year-old girl had a nonpruritic rash that initially appeared on her legs and arms. Lesions then spread to her face, hands, and buttocks; the trunk was spared. About 2 weeks earlier, the child had had a viral illness that lasted a few days; since then she had been healthy.

Photoclinic: Halo Nevus

March 01, 2007

A 13-year-old girl noticed that the skin around a "mole" on her abdomen had gradually changed color. This patient was told that she had a halo nevus--a pigmented (nevocellular) nevus surrounded by a tight ring of depigmentation--which is benign and usually regresses spontaneously over time. This relatively common lesion is believed to affect males and females equally. The development of the halo may coincide with puberty or pregnancy. Often, several pigmented nevi develop a halo simultaneously.

Photoclinic: Hereditary Hemorrhagic Telangiectasia

October 01, 2006

A 3-month-old infant was brought for evaluation after the sudden development of a tonic-clonic seizure that involved the left upper extremity. He had no history of fever, trauma, rash, refusal to suck, vomiting, diarrhea, upper respiratory tract infection symptoms, or bleeding. He was not taking any medications.

Photoclinic: Fragile X Syndrome

July 01, 2006

During a routine physical examination, a 3-year-old boy was noted to have speech delay and hyperactive behavior. The child was born at term to a 25-year-old mother with epilepsy, which was managed with phenytoin. His birth weight was 3.5 kg (7.8 lb); he had no neonatal problems or features of fetal Dilantin syndrome. However, he had undergone bilateral hydrocele and inguinal hernia repair and tube placement for recurrent ear infections. His half sister (from his mother's previous marriage) needs help in reading and math. His father is healthy.

Photoclinic: Poliosis

April 01, 2006

The lashes on this 12-year-old girl's right eye are white and gray; the lashes on the left eye are black. This small patch of white-gray hair, known as poliosis, occurs most often along the forehead (the so-called white forelock); however, hair anywhere on the body can be affected. The appearance in healthy persons simply indicates a lack of pigment in the hair and skin of the involved area.
