RESUMO

Basal cell carcinoma (BCC) is the most common malignant skin tumor which occurs more frequently over the sun exposed parts of body. Its adenoid variant is a rare histological subtype. We report a case of multiple adenoid basal cell carcinomas at unusual sites in a middle-aged male patient.

RESUMO

We report a case of acral lentiginous melanoma on the plantar aspect of foot in a 50-year-old male that exhibited a prominent osteo-cartilaginous differentiation in the metastatic inguinal lymph node. The ability of melanomas to undergo multidirectional differentiation leads to a variety of histological appearances that can be misleading. Although the true nature of the tumor is most often recognized at the primary cutaneous site, metastatic tumors may closely mimic other malignant mesenchymal or neuro-ectodermal tumors. Hence awareness of this unusual phenomenon occurring in malignant melanoma is essential to avoid misdiagnosis.

RESUMO

We report 2 cases of Follicular Dendritic Cell Sarcomas of Oral Cavity in two elderly patients. The patients presented with oral cavity tumors. Initial tru-cut biopsies in both cases revealed spindle cell neoplasms. One of them was of low grade malignancy and showed positivity for of Vimentin. Few cells showed positivity for keratin and were negative for S-100 protein, CD 34, CD 68, EMA, SMA, HMB-45. A possible diagnosis of low grade fibrohistiocytic tumor was made. He underwent Lt total maxillectomy. Three years later he presented back with regional nodal metastasis. The regional lymph nodes showed features of follicular dendritic cell sarcoma. The second case revealed high grade spindle cell neoplasm and showed positivity for vimentin and S100 protein and was negative for EMA, keratin, CD-34, desmin, muscle actin and HMB-45. He was offered initial radio-therapy followed by hemifacial resection. The histology along with immuno histochemistry favoured a diagnosis of follicular dendritic cell sarcoma. He presented with local recurrence two months later. Both the cases are discussed in detail.
