A skin biopsy is used to diagnose syringocystadenoma papilliferum. Characteristics of Syringocystadenoma papilliferum are dilated capillaries and a dense infiltration of plasma cells. [1] Differential diagnoses include papillary eccrine adenoma, warty dyskeratoma, tubular apocrine adenoma, and hidradenoma papilliferum. [3]
Papillary renal cell carcinoma (PRCC) is a malignant, heterogeneous tumor originating from renal tubular epithelial cells of the kidney, which comprises approximately 10-15% of all kidney neoplasms. [1] Based on its morphological features, PRCC can be classified into two main subtypes, which are type 1 and type 2 (eosinophilic). [2]
The renal cell carcinoma tends to be of the papillary (type 2) form and tends to occur more commonly in women than men with this syndrome. These cancers present earlier than is usual for renal cell carcinomas (typically in the twenties and thirties) and tend to be at relatively advanced stages at presentation.
Psammoma bodies are commonly seen in certain tumors such as: Papillary thyroid carcinoma [2]; Papillary renal cell carcinoma [3]; Ovarian papillary serous cystadenoma and cystadenocarcinoma [4]
Metanephric adenoma (MA) is a rare, benign tumour of the kidney, that can have a microscopic appearance similar to a nephroblastoma (Wilms tumours), [1] or a papillary renal cell carcinoma. It should not be confused with the pathologically unrelated, yet similar sounding, mesonephric adenoma .
Clear cell papillary renal cell carcinoma (CCPRCC) is a rare subtype of renal cell carcinoma (RCC) that has microscopic morphologic features of papillary renal cell carcinoma and clear cell renal cell carcinoma, yet is pathologically distinct based on molecular changes and immunohistochemistry.
Papillary eccrine adenoma is a cutaneous condition characterized by an uncommon benign sweat gland neoplasm that presents as a dermal nodule located primarily on the extremities of black patients. [ 1 ] : 668 [ 2 ] [ 3 ] [ 4 ]
Individuals with renal papillary necrosis due to excess use of analgesic have an elevated risk of epithelial tumors, hence a urine cytology exam is useful. [8] In terms of imaging this condition can be identified by retrograde pyelography (RGP). [9] The diagnosis of renal papillary necrosis is therefore done via: [10]
