ABSTRACT
Follicular mycosis fungoides is a distinct variant of mycosis fungoides. Clinically, it occurs mostly in adults, affecting more males than females. It is manifested as pruritic follicular papules, acneiform lesions, or indurated plaques, typically in the head and neck. Histopathologically, it is characterized by infiltration of atypical T lymphocytes with cerebriform nuclei in the follicular epithelium (folliculotropism). We report a case of follicular mycosis fungoides manifested as a milia-like lesion combined with the patch stage of mycosis fungoides, which was treated with radiotherapy.

Lichen Planus Pigmentosus (LPP), an uncommon variant of lichen planus, is clinically characterized by insidious onset of diffuse or reticulated hyperpigmented patches on the sun-exposed areas and flexural folds. Histopathologic findings of LPP show atrophic epidermis with vacuolar degeneration of the basal cell layer and sparse lichenoid lymphohistiocytic infiltration with melanophages in the dermis. Although there have been few reports of LPP, clinical and histological pathogenesis and prognosis are not well known. Herein, we describe a case of linear LPP along the Blaschko's lines in 34-year old Korean man who presented with linear hyperpigmented, dark brown patches on his left thigh, repeatedly developing new lesions of erythematous reticular patches since puberty. This report shows the early events of LPP and the protracted course.

BACKGROUND: Mohs micrographic surgery (MMS) is a specialized type of minimal marginal surgery, which offers superior cure rates to other options in the treatment of non-melanoma skin cancers. OBJECTIVE: The aim of this study is to investigate the clinical characteristics and recurrence rate of the non-melanoma skin cancer and to estimate the safeties of MMS. METHODS: We retrospectively evaluated 102 patients who had been diagnosed with non-melanoma skin cancer and treated by MMS from May 2008 to September 2011. RESULTS: The most common cancer was basal cell carcinoma (63.72%), followed by squamous cell carcinoma (31.38%). The local flap was the most common method to repair surgical defects (74.5%), followed by primary closure (17.64%). Cervical lymph node metastasis was confirmed in 1 case (0.98%). Recurrence after MMS was observed in 1 of 102 patients (0.98%). CONCLUSION: MMS is a safe method for the treatment of non-melanoma skin cancer.

Calcium channel blockers are widely used antihypertensive drugs, which are uncommonly associated with cutaneous reactions, such as pruritus, urticaria, or alopecia. Photosensitivity presenting with telangiectasia has rarely been described. We present here a case of photodistributed telangiectasia induced clinically by amlodipine and histologically by enlarged capillaries in the upper dermis without signs of vasculitis.

Erlotinib is a small-molecule tyrosine kinase inhibitor (TKI) of the epidermal growth factor receptor (EGFR). Erlotinib has been used primarily to treat non-small cell lung cancer. In addition to its role in tumor cells, EGFR is also an important regulator of growth and differentiation in the skin and hair. Therefore, EGFR-TKIs have been associated with a number of cutaneous side effects including follicular acneiform eruptions, cutaneous xerosis, chronic paronychia, desquamation, seborrheic dermatitis, and hair texture changes. Herein, we report a rare case of a 61-year-old woman who was treated with erlotinib and experienced cicatricial alopecia.

Common variable immunodeficiency (CVID) is one of the primary immunodeficiency disorders, which is characterized by hypogammaglobulinemia, defect in antibody synthesis and recurrent sinorespiratory bacterial infections. Granuloma is an uncommon skin manifestation in primary immunodeficiency disorders. Here we present a 5-year-old girl who had asymptomatic erythematous plaques on the face and legs. She had a past medical history of recurrent sinorespiratory and gastrointestical bacterial infections since 2 years old. The histopathologic findings of the skin lesions showed sarcoid-like granulomas with focal necrobiosis. No specific organism was found with evaluation. Cells forming granulomas were strongly positive for CD3 or CD68. CD4/CD8 ratio was estimated less than 1. Laboratory examination showed low hemoglobin, low B cell and normal T cell number, low IgA and IgG levels.

Disseminated superficial porokeratosis is a keratinization disorder characterized by multiple brown, atrophic patches with sharply demarcated and hypertrophic ridges. Atypical cases of disseminated superficial porokeratosis with acute exacerbation accompanied by severe pruritus have been reported as "eruptive pruritic papular porokeratosis" or "inflammatory disseminated superficial porokeratosis." We report a case of inflammatory disseminated superficial porokeratosis in a 53-year-old man who was successfully treated with oral isotretinoin.

Circumscribed palmar or plantar hypokeratosis is a rare dermatosis, and it consists of asymptomatic erythematous, well-circumscribed and depressed patch with scaly borders on the palm or sole. It usually affects middle-aged or elderly women. Histopathologically, it has a sharp stair between the normal and involved skin, and a demarcated area with an abrupt decrease in the horny layer thickness. We report herein a case of circumscribed palmar hypokeratosis that was successfully treated with cryotherapy.

Acromegaloid facial appearance (AFA) syndrome is a rare autosomal dominant disease, consisting of an acromegaloid face, a bulbous nose, and narrowing of the palpaebral fissure. In 1996, Irvin first reported a case of a combination of acromegaloid facial appearance syndrome and congenital hypertrichosis, and reported this case as a new disease of acromegaloid facial appearance with generalized hypertrichosis terminalis, which is differentiated from both AFA syndrome and congenital hypertrichosis/gingival hyperplasia. We report herein the first Korean case of acromegaloid facial appearance with generalized hypertrichosis terminalis.

Acantholytic squamous cell carcinoma is a well-defined, rare variant of squamous cell carcinoma in which significant portions of the neoplastic tissue show, on microscopy, a pseudoglandular or tubular pattern. It usually presents in aged patients as an erythematous nodule with scales, crust, and ulceration on sun-exposed areas. Herein we report a case of acantholytic squamous cell carcinoma that occurred on the Rt 4th toeweb of a 70-year-old man.

Pruritic urticarial papules and plaques of pregnancy (PUPPP), also known as a polymorphic eruption of pregnancy, is the most common dermatosis of pregnancy. Typically, PUPPP starts with erythema and urticarial papular eruption in the abdominal striae and may extend to the buttocks and thighs. It usually evolves in the third trimester and resolves rapidly in the postpartum. It is not usually recurrent in subsequent pregnancies. We report herein two patients with postpartum PUPPP.

Malalignment of the toenail is a rare deformity that is characterized by lateral deviation of the nail plate with respect to the longitudinal axis of the distal phalanx. The condition may be congenital or acquired. The acquired forms of malalignment may result from trauma or surgical intervention. However, there are only a few reports that have focused on surgical treatment for this condition. We present here a case of a 24-year-old woman who had this nail problem for 1 year and she was successfully treated with the surgical approach. We also discuss the probable mechanism of iatrogenic malalignment.

Apert syndrome is a rare genetic craniofacial disorder associated with premature fusion of multiple cranial sutures and syndactyly. It is caused by mutation in the fibroblast growth factor receptor 2 genes. The clinical findings are characterized by the typical dysmorphic facial features, including hypertelorism, proptosis and cleft palate. Most of these patients have widespread, severe acne involving the face, chest, back and forearms during puberty and the acne is unresponsive to conventional treatments. We report here on a patient with the recalcitrant acne of Apert syndrome and the patient had failed to respond to conventional acne treatment, but the acne was successfully treated with isotretinoin
