Most tumors diagnosed as basal cell tumors via cytology are easily cured with narrow surgical excision. If histopathology reveals a basal cell carcinoma, complete staging, including locoregional lymph node aspiration, chest radiography, and abdominal ultrasonography, is recommended.
26 kwi 2017 · MCTs originate from dermal mast cells. In dogs, mast cell tumours are the most common form of skin cancer and can appear as nodules or plaques of varying sizes, ranging from a few millimetres up to large masses.
A retrospective study was undertaken in which cytological features of basal cell tumours from 18 dogs and 12 cats were examined. Fine-needle aspiration biopsy was performed for cytological examination and diagnosis was confirmed on histopathological examination of excised tumour specimens.
16 lis 2023 · Basal cell tumors are diagnosed with cytology or a biopsy (i.e., histopathology). Fine needle aspiration (FNA), which involves collecting tumor cells for cytology using a needle and syringe, can be performed during a routine office visit without sedation.
Basal cell tumors vary in size, from a few centimeters to inches in diameter, and most commonly appear as single, firm, hairless, raised masses in the skin, often on the head, neck, or shoulders. Occasionally, they may be cystic or ulcerate, and some may stick out like stalks from the skin surface.
