| anonymous | Extramammary Paget's disease (100%) | Immunostains for cam 5.2, EMA and monoclonoal CEA to confirm diagnosis. Stains for melanocytic markers (S100 and HMB45) to exclude melanoma. | 100 |
| anonymous | Bowen disease | nil | 50 |
| anonymous | Frozen section diagnosis: positive for lesion, await paraffin section for definitive diagnosis. Differentials include extramammary Paget's disease and malignant melanoma. | Special stains to confirm Paget's (mucin, pCEA, Cam 5.2) Immunos to rule out melanoma (S-100 protein and HMB45) | 80 |
| anonymous | Extramammary Paget's disease | Confirm by immunostaining for Cam5.2 (+). Also exclude malignant melanoma (Cam5.2 negative, S100 positive) and Pagetoid Bowen's disease (Cam5.2 negative) | 100 |
| anonymous | Suspicious cells consistent with extramammary Paget's disease. 100% | To correlate with clinical findings eg any underlying carcinoma such as rectal carcinoma. Immunostains: S100 to rule out melanoma. Paget's disease should be +ve for CAM5.2 and CEA. | 100 |
| anonymous | Extramammary Paget's disease. (100%) | Nil. | 100 |
| anonymous | Scrotal skin - Extramammary Paget's disease 100% | To be supported by positive stains for mucin and CEA. | 100 |
| anonymous | Malignant cells in dermo-epidermal junction and dermis (100%), defer for paraffin for definitive diagnosis. | DD'x include 1) Extramammary Paget's disease, Bowen's disease and 3) melanocytic neoplasm. IH panel : CAM5.2 (for Paget's cells), Cytokeratins (for Bowenoid cells) and S100/HMB45 (for melanoma/melanocytic cells). | 100 |
| anonymous | Malignant tumor: 1) extramammary Paget's disease? 2) Superficial spreading malignant melanoma? | nil | 50 |
| anonymous | EXTRAMAMMARY PAGET'S DISEASE (100%) | nil | 100 |
| anonymous | Paget's disease 100% | Cam 5.2, CK7/20 to confirm BRST-2 to support primary appendageal origin S100/HMB45 to exclude melanoma LCA to exclude lymphoma | 100 |
| anonymous | Extramammary Paget’s disease | Suggest excluding underlying genital malignancy | 100 |
| anonymous | Paget’s disease, extramammary. Probability: 100% | nil | 100 |
| anonymous | Extramammary Paget's disease (90%), Bowen'sdisease (10%) | Extramammary Paget's disease can be confirmed by performing mucin stain and immunostains for CEA and EMA; Bowen's disease is negative. | 100 |
| anonymous | Extramammary Paget's disease (100%) | S-100 protein to exclude melanoma. | 100 |
