Halogenoderma: A Case Report and Review of the Literature.

Halogenoderma (HD) is an uncommon dermatosis that develops following exposure to halogens such as iodide and bromide, referred to as iododerma and bromoderma, respectively. Here, we report the case of a 40-year-old male who presented with a three-week history of slightly itchy progressive skin lesions associated with low-grade fever and malaise. The patient had a history of using food supplements containing iodide and bromide for four months prior to the appearance of skin rashes. Skin examination revealed multiple crusted papules and nodules scattered on his face, neck, and trunk. A skin biopsy was taken from the lesions. The epidermis showed crustation, exocytosis of neutrophils, and multiple intraepidermal abscesses. The dermis showed heavy cellular infiltrates composed mainly of neutrophils. The skin lesions disappeared completely after the cessation of food supplements, along with the use of topical corticosteroids for a few weeks.

Nodular hidradenocarcinoma of the forehead presenting as a lipoma: A case report with a review of literature.

INTRODUCTION: Hidradenocarcinoma is an uncommon slow-growing malignant tumor that originates from sweat glands, it is most seen in the head and neck, and present typically as hard asymptomatic nodule. Diagnosis is confirmed by histopathology and immunohistochemistry, and wide local excision is the mainstay of the treatment. In our study, we discuss the approach and management of this rare disease, with focusing on the importance of histopathology in diagnosing such cases. PRESENTATION OF CASE: We present a very rare case of a 58-year-old female who presented with painless slow growing forehead swelling for 2 years, with clinical feature suggestive of lipoma. The patient underwent surgical excision, and post-operative histopathological examination of the specimen was consistent with nodular hidradenocarcinoma. DISCUSSION: Hidradenocarcinoma is a very rare malignant tumor that was first reported in 1954. This tumor was reported to be more common in males, and the incidence increases with age. The origin of hidradenocarcinoma is mostly de novo. The definitive diagnosis requires histopathological examination, and wide local excision is the mainstay of the treatment. CONCLUSION: Hidradenocarcinoma is a very rare sweat gland malignancy, and the diagnosis can be challenging. In our study, we emphasize the importance of raising the awareness among the surgical oncology society regarding this rare tumor, and we discuss the approach and management of such an uncommon disease, with focusing on the importance of histopathology in diagnosing such cases.

Reconstruction of facial dermatofibrosarcoma protuberans using an anterolateral thigh flap: a case report and literature review.

Dermatofibrosarcoma protuberans is a rare, locally aggressive cutaneous malignancy with a high rate of recurrence if the head-and-neck region is involved. Treatment is challenging as it is difficult to avoid poor aesthetic and functional outcomes using the standard approach of complete resection with negative margins and subsequent reconstruction. This is especially challenging in cases where the face is involved and the defect is large after resection. There have been few cases of reconstruction using different flaps reported. We present the case of a young lady with a large cheek tumor, which was reconstructed using an anterolateral thigh flap. Excellent functional and aesthetic outcomes were achieved.
