Eccrine poromas arise from the intraepidermal region of the eccrine sweat duct and most often occur as a benign solitary tumor. There are few reports of the occurrence of multiple lesions, defined as poromatosis, which may present in patients who have undergone radiotherapy and/or polychemotherapy. We report the case of a 43-year-old male with a history of mantle cell lymphoma who had undergone...

Dear Editor, Apocrine hidradenoma is a rare benign adnexal tumor related to the more common poroma, as they both originate from sweat glands. Hidradenoma usually has an eccrine differentiation, but an apocrine differentiation is possible. Due to its rarity and non-specific clinical appearance it is difficult to differentiate it from other malignant cutaneous lesions. In this challenging task, d...

An eccrine nevus is a rare hamartoma characterized by an increase in the number or size of eccrine glands. Eccrine nevi usually present as localized hyperhidrosis and are not associated with overlying skin abnormalities. However, among the cases that have been reported in the literature, some unique presentations of eccrine nevi have been demonstrated, including a pigmented patch, a depressed n...

Eccrine porocarcinoma is a rare malignant adnexal tumor of ductal portion of eccrine sweat gland. It occurs commonly in the lower extremities and rarely in scalp, face, ear, trunk and upper extremities. This survey presents a classic case of eccrine porocarcinoma of scalp in a 58 yr old male patient, presenting as cauliflower like growth over parietal aspect of scalp.  

Eccrine angiomatous hamartomas are benign vascular and eccrine malformations often accompanied by hyperhidrosis or pain, increased eccrine glands, and aggregates of vessels. Verrucous hemangiomas are congenital vascular malformations presenting as unilateral grouped papules. Histologically, they show verrucous epidermal change and proliferation of capillaries in the dermis. We report a case of ...

Porokeratotic eccrine and hair follicle nevus is a very rare non-hereditary disorder of keratinization with eccrine and hair follicle involvement with only 9 cases described in the literature. In 2009 the term porokeratotic anexial ostial nevus was proposed to comprehend porokeratotic eccrine and hair follicle nevus and a related and more common process without follicular involvement: porokerat...

UNLABELLED Malignant eccrine spiradenomas are exceedingly rare tumours. They are aggressive tumours normally arising in long-standing benign eccrine spiradenomas. We present a case of malignant eccrine spiradenoma of the right side of the face with direct intracranial extension without distant metastasis. A 48 years old woman presented with a large exophytic tumour on the right side of her face...

Eccrine spiradenoma is an uncommon benign adnexal tumor originating from the eccrine sweat gland. We diagnosed a eccrine spiradenoma on a 55-year-old man with histopathologic confirmation upon biopsy followed by complete resection, who had visited our clinic with a chief complain of occipital scalp mass. The solitary eccrine spiradenoma occurring in the scalp is rarely to be seen and should be ...
