Vellus hair follicle Accessory auricle Trichofolliculoma Hair nevus Abstract We present a case of hair follicle nevus, a rare hamartoma composed of vellus hair follicles. Hair follicle nevus should be differentiated from accessory auricle, trichofolliculoma and hair nevus.

accessory components. By collapsing the unnecessary space and reconstructing a new tragus, we achieved an ideal distance from the new tragus to the auditory canal, which could not be attained by filling the hollow using cartilage graft. Because the shape and conditions of polyotia are very inconstant and the incidence of this anomaly is rare, it is difficult to establish a uniform surgical tech...

Mitral atresia is a rare congenital anomaly, but its true incidence is difficult to assess. In 1962, Fontana and Edwards reported 8 cases of isolated mitral atresia and found 24 others in published reports. They also described 5 cases of combined mitral and aortic atresia and found 23 other published cases. From Britain, MacMahon, McKeown, and Record (1953), in a careful survey of congenital he...

1. Action potentials from sinus venosus and auricle fibers of spontaneously beating frog hearts have been recorded with intracellular electrodes. 2. Sinus fibers show a slow depolarization, the pacemaker potential, during diastole. The amplitude of this potential varies in different parts of the sinus. In some fibers the membrane potential falls by 11 to 15 mv. during diastole and the transitio...

The intestinal absorption of calcium and magnesium was measured by metabolic balance studies in 6 normal infants, 13 infants with biliary atresia, 5 infants with successfully repaired biliary atresia, 7 i...

BACKGROUND Pseudocyst of the auricle is a common benign disease. Many treatment modalities have been described for this benign condition ranging from simple aspiration to complex cutaneous surgeries involving skin de-roofing and debridement with diamond burr. the aim of treatment is to successfully resolve the seroma without damaging the underlying healthy cartilage, thus maintaining the norma...

this manuscript reviews the present knowledge related to folliculogenesis in sheep.folliculogenesis starts with formation of primordial follicles before birth, present as a pool containing a certain number of follicles. by the attainment of puberty, a group of follicles from that pool starts to grow, a process known as primordial follicle activation or recruitment. the number of growing primord...
