Immunofluorescent studies of complement C3 in the hair follicles of normal scalp and of scalp affected by alopecia areata.

The deposition of complement C3 in the hair follicles of scalps of 4 normal subjects and of the affected parts of 9 patients with alopecia areata was found by the direct immunofluorescent methods. No deposition of immunoglobulins (IgG, IgA, IgM, IgD and IgE) was found. In the normal scalps, complement C3 was found to be deposited in the hyaline membrane of the hair bulb and in the internal layer of connective tissue sheath at the lower about 2/3 transient portion of anagen follicles, and in the thickened hyaline membrane of the catagen follicles. The deposition of complement C3 was also found in the anagen and catagen-like hair follicles even in the patients with alopecia areata, which was similar to the finding in the normal scalps. From the fact that the deposition of complement C3 was found chiefly in the transient portion of the hair follicles of the normal scalps, and that the behavior of deposition of complement C3 reflected the morphological state of hair follicles in each stage of the hair cycle, even in alopecia areata, complement C3 may be intimately related to the hair cycle, even though its significance is as yet unknown.

Dystrophic xanthomatosis in mycosis fungoides.

The condition of a patient with advanced mycosis fungoides was treated with cyclic combination chemotherapy. At the sites of regressing tumors, yellow nodules appeared that were clinically and histologically benign xanthomata. The probable multifactorial pathogenesis of dystrophic xanthomata is discussed and previous case reports are reviewed.

Histologic and ultrastructural features of the ichthyotic skin in X-linked dominant chondrodysplasia punctata.

The ichthyotic skin in X-linked dominant chondrodysplasia punctata was investigated in a four-week-old baby and a fourteen-year-old girl. Histologically, the ichthyosiform erythroderma of the newborn and the ichthyosis of the older child presented as a retention hyperkeratosis with several distinctive features such as calcification of the keratotic follicular plugs, atrophy of the hair follicles and focal hyperpigmentation of the basal keratinocytes. On ultrastructural examination, small to medium sized vacuoles were regularly seen in the thinned granular layer. Some of these vacuoles contained needle-like calcium inclusions. The histologic and ultrastructural findings are therefore characteristic for this rare type of ichthyosis.
