Assignment Help:

Spider Naevus:

It  is found on  the cheeks,  nose  and  sometimes other parts of the  face  as a central  bright-red vessel about  the size of  a pin-point with smaller vessels radiating  from  it  of  3 to 7 mm. Since  this picture resembles  the body  and legs of  the  spider, it  is called spider  naevus.  One or more of  these  lesions may occur  in  a  single  individual. A spider naevus  bleeds easily. Management consists of  obliterating the central  point with electrolysis or with the epilating current  of a  diathermy unit. The results are satisfactory in experienced  hands. 

Simple Superficial Capillary Haemangioma:

It  is seen  as a  superficial circumscribed, pink  patch,  which disappears on pressure or diascopy.  It  is usually  seen on  the  neck  and  face,  It  responds best  to Thorium X-ray and Laser.
