Anhidrotic ectodermal dysplasia (AED) is characterized by a well-known tetrad of anhidrosis, hypotrichosis, hypodontia, and typical facies with a wide constellation of developmental defects of tissues derived from the ectoderm. Most of these patients have normal or borderline normal intelligence, but some present with mental retardation. A 15-year-old boy and his younger brother were evaluated for dry skin and intolerance to heat since their births. Their parents and other brother were normal. Both of them had atopic dermatitis. A skin biopsy was done on their left axilla, which showed a few immature eccrine glands in the dermis. We report herein two rare cases of AED in siblings with atopic dermatitis.

We report a rare case of sporadic keratosis punctata palmaris et plantaris in a 49-year-old woman. Thirty years ago, firm semitranslucent papules developed on the middle portion of her palms without any subjective symptom. The lesions had flat-topped smooth surfaces. They were concentrated along the margins of the hands, especially on the lateral surfaces of both index fingers and finger tips/ Ten years ago, similar hyperkeratotic papules with or without central craters developed on the weight bearing portions of her soles. Her family and past histories were negative. The biopsy specimen revealed a dense hyperderatotic stratum corneum which fitted into a cup shaped depression in the stratum malpighii and a turning inward of the rete ridges at the margin. The Masson trichrome and elastic strains showed no peicific dermal changes.

We report two cases of malignant lymphoma of mucosa-associated lymphoid tissue arising in the conjunctiva. Case 1, an 18-year-old girl, showed her left lower conjunctival swelling for four months and Case 2, a 29-year-old man, showed similar lesions on both his eyes for one year. Histologically, both cases revealed monomorphous dense lymphoid infiltrates invading the overlying conjunctival epithelium with diffuse patterns. The infiltrates were composed of small lymphocytes admixed with centrocyte-like cells within the conjunctival epithelium and stroma in association with B-cell lineage. No relapse was noted during the period of about 1½ years follow-up in case 1 treated by local excision only and in the follow-up period of 2 months in case 2 treated by local excision and subsequent chemotherapy.

We report a case of atrophoderma vermiculata with an unusual location. Besides symmetrical small pitted macules and linear atrophic depressions on both cheeks, there were unilateral atrophic depressed macules on the forehead, the right popliteal fossa and left up-per arm in our case. The histopathologic findings of these lesions showed a slight degree of epidermal atrophy with follicular pluggings and flattened rete ridges. In the dermis, there were mild perivascular in-filtrations of mononuclear cells. In addition, we could find out no pilosebaceous unit and other adnexal structures were diminished in number.

PURPOSE: To date, the high spatial frequency algorithm (HSFA) which reduces image smoothing and increases spatial resolution has been used for the evaluation of parenchymal lung diseases in thin-section high-resolution CT. In this study, we compared the ultrahigh spatial frequency algorithm (UHSFA) with the high spatial frequency algorithm in the assessment of thin section images of the lung parenchyma. METHODS AND MATERIALS: Three radiologists compared the UHSFA and HSFA on identical CT images in a line-pair resolution phantom, one lung specimen, 2 patients with normal lung and 18 patients with abnormal lung parenchyma. RESULTS: Scanning of a line-pair resolution phantom demonstrated no difference in resolution between two techniques but it showed that outer lines of the line pairs with maximal resolution looked thicker on UHSFA than those on HSFA. Lung parenchymal detail with UHSFA was judged equal or superior to HSFA in 95% of images. Lung parenchymal sharpness was improved with UHSFA in all images. Although UHSFA resulted in an increase in visible noise, observers did not found that image noise interfered with image interpretation. The visual CT attenuation of normal lung parenchyma is minimally increased in images with HSFA. The overall visual preference of the images reconstructed on UHSFA was considered equal to or greater than that of those reconstructed on HSFA in 78% of images. CONCLUSION: The ultrahigh spatial frequency algorithm improved the overall visual quality of the images in pulmonary parenchymal high-resolution CT.
