Parthenium dermatitis presenting as photosensitive lichenoid eruption. A new clinical variant

Parthenium hysterophorus is the commonest cause of airborne contact dermatitis (ABCD) in India. The disease usually manifests as itchy erythematous, papular, papulovesicular and plaque lesions on exposed areas of the body. Rarely, however, the disease may present as actinic reticuloid or photocontact dermatitis. We have observed a different clinical variant of this disease where certain patients with Parthenium dermatitis have presented with discrete, flat, violaceous papules and plaques on exposed areas of the body closely simulating photosensitive lichenoid eruption. We had 8 patients, 6 males and 2 females between 30 and 62 years of age, with itchy, violaceous, papules and plaques on the face, neck, ears, upper chest and dorsa of the hands for 6 months to 6.5 years. Four of these patients had a history of improvement of the lesions up to 30% in winter and aggravation of lesions on exposure to sunlight. There was no personal or family history of atopy. Cutaneous examination in all patients revealed multiple flat, violaceous, mildly erythematous papules and plaques on the forehead, sides and nape of neck, ears, 'V' area of the chest, and extensor aspects of the forearms and hands. Skin biopsies from these lesions showed features of chronic non-specific dermatitis. Patch testing with standardized plant antigens showed a positive patch test reaction to Parthenium hysterophorus in all patients, with a titre of contact hypersensitivity (TCH) varying from undiluted to 1 : 100. We conclude that Parthenium dermatitis may occasionally present with lesions very similar to the lesions of photosensitive lichenoid eruption in morphology and distribution. This clinical presentation of Parthenium dermatitis needs to be recognized to avoid misdiagnosis.

Pseudoacne of the Nasal Crease: A New Entity?

In this article we describe a clinical entity appearing in seven preadolescent patients who presented with chronic red papules within a prominent nasal crease. Milia were also noted in the nasal crease, but there was no evidence of acne vulgaris. The duration of symptoms was 4 months to 2 years, and lesions ranged from inflamed red papules, which were treated with topical antiinflammatory medications, to scarred white papules requiring excision. Histologic evaluation of two lesions revealed keratin granulomas that were likely derived from ruptured, inflamed milia. Due to its similarity in appearance to acne vulgaris, but different pathogenesis and clinical course, we suggest naming this newly described entity "pseudoacne of the nasal crease."     

Spontaneous resolution of facial papular mucinosis in a transplant patient

A 37-year-old male developed facial papules 6 months post renal–pancreatic transplant. Histological findings were consistent with localized papular mucinosis; electrophoresis showed no paraprotein. A trial of erbium and aura lasers, at ablative doses, produced no improvement. Independent treatments with oral doxycycline, itraconazole, acitretin, and isotretinoin also had no effect. The facial papules improved spontaneously, 2 years after first presentation and 8 months after treatment ceased. The patient remains clear of lesions.

恶性萎缩性丘疹病一例

患者，女，58岁。躯干四肢散在红斑丘疹4个月余。皮肤科检查：躯干四肢散在红斑丘疹，丘疹中央可见瓷白色萎缩性斑片，边缘隆起伴红晕，伴腹痛。皮损组织病理示：表皮萎缩变薄，真皮浅中层胶原变性，血管周围散在小片状的淋巴细胞及组织细胞浸润。诊断：恶性萎缩性丘疹病。给予阿司匹林、双嘧达莫、雷贝拉唑钠、美沙拉嗪、阿嗪米特口服治疗1个月后腹痛症状缓解，全身皮疹颜色变淡。2个月后患者腹痛加重诊断为肠穿孔，术后无明显改善。4个月后去世。     

Truncal lesions do not exclude a diagnosis of Gianotti-Crosti syndrome

A boy aged 2 years and 10 months had a pruritic eruption and low-grade fever for 1 week. Examination revealed discrete erythematous papules and papulovesicles on his buttocks and extensor surfaces of four limbs. Several papules were also present on his back. No lymphadenopathy and no hepatosplenomegaly were noted. Investigations failed to identify a single viral aetiology. Topical calamine lotion and a sedating oral antihistamine to be taken at night were prescribed. The truncal lesions subsided in 3 weeks. Complete remission of all lesions was seen after 6 weeks. Although most patients with Gianotti-Crosti syndrome only have the typical acrally distributed eruption, additional truncal lesions, if few in number, do not exclude the diagnosis.     

Generalized lichen nitidus

Lichen nitidus is a rare chronic condition of unknown etiology. Generalized lichen nitidus is even rarer. We report here a 5-year-old girl who had multiple, asymptomatic, discrete, 1 to 2 mm flesh-colored, shiny, flat, papules on her face, upper limbs, and thighs with relative sparing of the trunk. Resolution of these papular lesions was followed by hyperpigmented macules in those areas. Histopathologic examination of a papular lesion revealed a localized granulomatous lymphohistiocytic infiltrate in an expanded dermal papilla with thinning of overlying epidermis and downward extension of the rete ridges at the lateral margin of the infiltrate, producing a typical "claw clutching a ball" picture, confirming our clinical diagnosis of lichen nitidus. The pigmented macules showed melanin pigmentation on histology. There was no response to oral astemizole treatment for 3 months. However, the lichen nitidus lesions resolved spontaneously without any further treatment over the next year, leaving behind a prominent pigmentary disturbance.
