    Abstract:
    Background: Skin adnexal tumours are a category of rare tumours. They usually present as painless nodules and papules. The diagnosis of these tumours poses a challenge, because there is usually a discrepancy in clinical and histopathological diagnosis. Aims: To study the skin biopsies received in our department and compare their clinical and histopathological diagnosis. Material and methods: Prospective study of skin biopsies received in our department over a period of 1 year. The biopsies were processed and stained with haematoxylin and eosin and studied under the light microscope. Results: Out of the 26 cases studied, 25 were found to be benign tumours with a single case of keratoacanthoma. The most common tumour encountered was pilomatricoma and the least common was syringoma. Only four cases showed clinical correlation with histopathological diagnosis. Conclusion: It can be therefore concluded that skin adnexal tumours are rare tumours which need histopathological examination for their accurate diagnosis.

    Benign adnexal tumors of the skin, excluding pilomatrixomas, were identified in 28 patients between the ages of 4 and 20 years with a mean age of 15; 23 women and 5 men. Most lesions were described as papules and they occurred on the face, scalp and neck in 75% of cases. Trichoepithelioma and syringoma accounted for 56% of all neoplasms. Only one patient gave a history of familial trichoepitheliomas. The remaining tumors were examples of syringocystadenoma papilliferum, eccrine acrospiroma, and eccrine and apocrine hidrocystomas. Excisional biopsy constituted the treatment in all cases; only one neoplasm, an eccrine acrospiroma, recurred locally.

    In Reply.—

    Thank you for forwarding Dr Arnold's letter regarding the spelling of pilomatricoma. We were aware at the time of submitting our LETTER TO THE EDITOR of the correct spelling of pilomatricoma; however, because of current usage and the appearance of the word pilomatrixoma in all of the current text, we elected to perpetuate an unfortunate error. Certainly Dr Arnold is entirely correct in his spelling of the calcifying epithelioma of Malherbe. Thanks again to Dr Arnold for again reminding us of this repeated error.

    Epithelioma
    Pilomatrixoma, also known as pilomatricoma is a rare benign appendageal neoplasm of hair follicle matrix. It usually presents as a superficial, firm mass, commonly found in the head and neck region which may pose a diagnostic challenge as it may resemble other common benign lesions as in this case, sebaceous cyst. Pilomatrixoma remains to be misdiagnosed and are usually not considered in differential diagnosis. We report a case of a young girl with pilomatrixoma of neck, surgical management and histopathological findings.

    Pilomatricoma is a benign appendageal tumour originating from the hair matrix. The lesion is usually a solitary, deep dermal or subcutaneous, firm-to-hard, lobulated mass. However, patients with multiple lesions, and rarely bullous or anetodermic changes have been reported. We report two cases presenting with bullous pilomatricoma.

    Pilomatrixoma, a benign skin appendageal tumor, is seen commonly in head and neck. Pilomatrixoma also known as pilomatricoma or calcifying epithelioma of Malherbe. These lesions are typically found in the head and neck region, but also occur in the upper extremities and are rarely reported in other sites. Most cases of pilomatrixoma occur in children under the age of 7 and the condition is twice as common in females as in males. Pilomatrixomas are frequently misdiagnosed when the evaluation is based on clinical or radiographic examination alone. Therefore, the final diagnosis requires histopathological examination.

    To the Editor.—

    I definitely agree with Dr. Arnold's opinion. In my manuscript submitted for publication, "pilomatricoma" was used. However, I was informed by the copy editor that the change to "pilomatrixoma" was necessary to conform to the spelling ofStedman's Medical Dictionary. I am sorry that, with my limited knowledge of English, I decided to give in.
