Idiopathic livedo reticularis may be associated with ulcerations of the lower extremities beginning primarily during the warmer or summer months, as well as the more usual occurrence of winter ulcerations. Summer ulceration apparently is a new and rare entity which has many clinical and histopathologic features similar to winter ulcerations. Hypertension, Raynaud's phenomena, acrocyanosis and t...

The clinical and histopathologic features of a case of ameloblastic fibroma in a 9-year-old boy has been presented along with a review of the literature. The tumor responded to conservative surgical treatment and there was no recurrence one year postoperatively. Analysis of the literature suggests that the tumor may have a higher potential for recurrence than is generally appreciated. In additi...

BACKGROUND Lobular keloid appears to be a consequence of hypertrophic inflammation secondary to ear piercings performed under unsterile conditions. We wish to understand the pathogenesis of lobular keloids and report operative outcomes with a literature review. METHODS A retrospective review identified 40 cases of lobular keloids between January, 2005 and December, 2010. Patient records were ...

Hypertrophic cardiomyopathy (HCM) is characterized by the presence of an abnormal hypertrophy of the left ventricle (LV), without dilation, and in the absence of any condition or another cardiac or systemic disease capable of inducing such hypertrophy. This primary or idiopathic hypertrophy can occur with or without dynamic obstruction (induced by exercise) of the LV outflow tract, so in its na...

We reported two cases of clinically typical melasma presenting with unusual histopathologic findings. In one case, the epidermal melanocytes were markedly increased in number and protruded into the dermis, and in the other case, increased epidermal pigmentation as well as dermal melanocytosis were found. We suggested that the various treatment modalities of melasma should be applied depend on i...

Angiolipoma is a rare, benign variant of lipoma; its distinctive feature is its prominent vascularity. It presents as a subcutaneous nodule of white adipose tissue; pain, which may be exacerbated by pressure, is the chief symptom. The anatomic distribution predominantly involves the trunk and extremities. Because of the rarity of this condition in otorhinolaryngology, our understanding of its d...
