Spindle cells are specialized cells that are longer than they are wide. They are found both in normal, healthy tissue and in tumours. The most common type of normal spindle cell is called a fibroblast. Fibroblasts are support cells that are found in a type of connective tissue called stroma. Tumours made up of spindle cellsSpindle cell is a description of the type of cells the tumor is composed of. For example, there are round cell tumors and giant cell tumors. The prognosis can vary depending on the final diagnosis. Many of these types of cancers do not have good prognosis which may explain the contrast in opinion.Spindle cell lesions of the breast comprise a heterogeneous group of lesions, ranging from reactive and benign processes to aggressive malignant tumours. Despite their rarity, they attract the attention of breast pathologists due to their overlapping morphological features and diagnostic challenges, particularly on core needle biopsy (CNB ... Spindle cell carcinoma is a rare biphasic tumor consisting of epithelial and mesenchymal components. Presence of this tumor type in the tongue has rarely been reported. Herein, a case of 55-year-old woman who presented with a polypoid lesion at her tongue has been reported. Surgery was performed and pathologic examination revealed a spindle cell carcinoma.Spindle cells are of mesenchymal origin, and form the body's connective tissue, fat, muscle, bone, cartilage and blood vessels. The name 'spindle cell' refers to the shape of the cell on cytology and histology. Spindle cell tumours can be benign (suffix -oma) or malignant (suffix -sarcoma), and will arise from these different cell lines.An atypical pigmented spindle-cell nevus: a small multicolored lesion showing irregular and ill-defined borders.

It is generally found on the trunk or lower extremities of young women. Most authors consider it to be a variant of Spitz nevus. The main concern with these lesions remains their propensity to mimic melanoma both clinically and histologically.Spindle cell sarcoma is an uncommon cancerous lesion or tumor that forms in an individual's soft tissues or bone. The most prominent locations for spindle cell sarcoma to develop are in the limbs, but it can form in any part of the body.Abdominal-pelvic masses containing spindle cell and fibroblastic proliferation are very rare.

Histologically, the striking feature of this lesion was attributed to the presence of spindle cells arranged in a diffuse pattern, which is a pitfall for diagnosis. Spindle Cell Squamous Cell Carcinoma of Skin may appear as skin lesions, commonly on sun-exposed areas, mostly involving the head and neck region. The lesions may ulcerate and cause scarring of skin The treatment of choice is a surgical excision with clear margins followed by radiation therapy or chemotherapy, as decided by the healthcare provider.Since spindle cell carcinoma seems to grow expansively within its circumscribed boundary (3, 5, 6) and to exhibit a low incidence of lymph node metastasis (3, 5, 8), its malignant potential is likely to be lower than expected from its tumor size.
