Hidradenocarcinomas are very rare malignant sweat gland tumors that possess an infiltrative and/or low metastatic potential. Here we describe an interesting case of hidradenoma on the fronto-parietal region of the scalp of an elderly female, part of which had developed carcinomatous changes, infiltrating up to the pericranium. She developed intense itching, pain, spontaneous ulceration and rapid increase in the size of the tumor correlating with the expression of malignant behavior of the neoplasm. An initial incision biopsy suggested features of benign poroid hidradenoma, while the histology from the excised tumor exhibited a fairly well circumscribed epithelial neoplasm in dermis consisting of interconnected nodules as well as differentiated ducts, the neoplastic cells showing mild pleomorphism of nuclei, mitotic figures and abundant pale cytoplasm. Clefts, sclerotic stroma and foci of necrosis en mass were also seen. The final diagnosis was a well differentiated and slow growing hidradenocarcinoma. The tumor recurred locally despite total excision.
A chondroid syringoma (CS) is an exceedingly rare mixed tumor of the skin. These tumors are relatively common in the head and neck area. Occurrence of these tumors in the philtrum is rare, with only two documented cases in English literature to the best of our knowledge. This paper presents a case of CS of the philtral dimple with aesthetically excellent philtrum reconstruction.
A 30-year-old female presented to us with multiple tender erythematous papules and nodules. These lesions showed multi-segmental distribution along 5(th) cervical, 6(th) dorsal, and 1(st) sacral segments of right half of the body. Histopathological examination confirmed the clinical diagnosis of leiomyoma. Patient was started on nifedipine 10 mg thrice-daily with significant symptomatic improvement in 3 months. Though segmental distribution of leiomyoma is common, unilateral multi-segmental distribution has not been so far reported in the literature. Hence, the case is being reported for its rare presentation and the need for long-term follow-up in view of its association with aggressive renal carcinoma.
