Soft tissue expansion technique has been a very useful method for the reconstruction of scalp defects and alopecia since the scalp is an unyielding tissue allowing minimal distension in traditional local flap surgery. As a result, there has been wide use of the tissue expansion method in the reconstruction of scalp defect and treatment of alopecia in the plastic surgery. There have been many concerns about histomorphologic changes of the overlying skin and the underlying structure resulting from tissue expansion. We also know that progressive tissue expansion induces increased mitotic activity of the epidermis and thining of the dermis in the overlying skin, as well as significant gross, histologic bony erosion in the underlying structure. However, little informations have been reported about the changes of the hair and pilocebaceus units in scalp expansion. We compared the horizontal sections of the expanded scalp and its longterm histologic changes with a normal unexpanded scalp specimen as a control. The terminal hair proportions to the vellus hair both increased. There was a 32% decrease in follicular units, a 24% decrease in terminal hair, and a 23% decrease in total hairs 8 week after scalp expansion compared to the normal unexpanded scalp. The perifollicular inflammatory changes and fibrosis observed in the full expanded scalp specimen disappeared within 12 weeks after removal of the expander and the flap transposition. In our observation, tissue expansion at the hair-bearing scalp did not precipitate any adverse changes on the hair follicles. On the contrary, we observed that secondary scalp expasion could be safetly performed 3 months after the first scalp expansion.

Colorectal Neoplasms*

We report herein a case of polymorphic pemphigoid in a 65-year-old woman, who had one-year history of generlized polymorphic eruption with intensely pruritic excoriated vesicobiullous lesions and residual pigmentation. Face and oral mucosa were spared. The skin biopsy specimen showed a subepidermal blister containing many eosinophils. Linear deposition of 1gG and C3 along the basement membrane was noticed on direct irnmunofluorescerice. Polyclonal garnmopathy with a tendency of beta-gamma bridging and increased IgG, IgA and kappachain, was frund on serum protein electrophoresis and immunoelectrophoresis. Skin lesions were well coritrolled by a combined therapy of prednisolone(20 mg/d), dapsone(100 mg/d) and cyclophosphamide(100 mg/d) for 4 months. Direct immunofluorescence performed 11 rnonths after the cnmpletion of the therapy was negative.

Angioedema is a disorder characterized by well-demarcated nonpitting edema involving the tongue, floor of the mouth, larynx, lips, and face. The incidence of angiotensin converting enzyme(ACE) inhibitor related angioedema has been reported to be about 0.1% to 0.2%, and the time of onset is usually during the first week of therapy. These ACE inhibitors include captopril, enalapril, and lisinopril. A 53-year old man with an 8 month history of hypertension previously controlled with atenolol, was presented to the dermatologic department with angioedema of the face and tongue. He had begun therapy with captopril one day before this episode. Even though he was treated with epinephrine and methylprednisolone sodium succinate, the edema gradually progressed and finally dyspnea developed. He was urgently intubated and treated with steroids and pheniramine maleate in the intensive care unit. The edema resolved after 24 hours.
