Tumors Of The Hand

Background: Benign soft-tissue tumors of the hand are more common than both their benign bone and malignant soft-tissue counterparts. This study evaluates the characteristics and treatment of benign soft tissue tumors in light of 1 institution’s experience. Methods: Histologically confirmed benign soft-tissue tumors of the hand were retrospectively identified using International Classification of Disease codes from 1992 to 2015. A medical chart review was conducted to collect patient demographics, tumor epidemiology, and treatment. Results: A total of 199 soft-tissue tumors were identified. The median patient age at time of treatment was 47.4 ± 14.7 years in age. The majority of tumors were located in the digits (n = 168, 84%) and treated by excision (n = 191, 96%). Localized type tenosynovial giant cell tumors (n = 71, 36%) were the most common and had the highest rates of recurrence (8.5%) in this series. Other frequent histologies included hemangioma, schwannoma, and glomus tumors. Conclusion: Awareness and understanding of tumor characteristics may help physicians with diagnosis and treatment. There is an extensive variety of tumors, but the principles of clinical and imaging diagnosis are common to all of them. Marginal excision for the treatment pain, improvement of function, and cosmetic correction applies to all these tumors independent of the histology.

Response To Chemotherapy

: Differentiation of malignant from benign soft tissue tumors is challenging with imaging alone, including that by magnetic resonance imaging and computed tomography. However, the accuracy of this differentiation has increased owing to the development of novel imaging technology. Detailed patient history and physical examination remain essential for differentiation between benign and malignant soft tissue tumors. Moreover, measurement only of tumor size based on Response Evaluation Criteria In Solid Tumors criteria is insufficient for the evaluation of response to chemotherapy or radiotherapy. Change in metabolic activity measured by 18F-fluorodeoxyglucose positron emission tomography or dynamic contrast enhanced-derived quantitative endpoints can more accurately evaluate treatment response compared to change in tumor size. Magnetic resonance imaging can accurately evaluate essential factors in surgical planning such as vascular or bone invasion and “tail sign”. Thus, imaging plays a critical role in the diagnosis and treatment of soft tissue tumors.

Benign Soft Tissue Tumors

Purpose: The spectrum of diagnoses and clinical features of hand tumors differ from those of tumors in other body parts. However, only a few reports have comprehensively referenced the diagnosis and clinical features of hand tumors. This study aimed to elucidate the diagnostic distribution and the clinical features of hand tumors undergone surgery in our institute. Patients and methods: A total of 235 lesions in 186 patients diagnosed with hand tumors between 1978 and 2020 were reviewed. Age at surgery, gender, chief complaint, tumor location, and pathological diagnosis were analyzed. Results: There were 121 benign bone tumors, 98 benign soft tissue tumors, and 16 malignant tumors. Chondroma and tenosynovial giant cell tumor were common benign bone and soft tissue tumors at the proximal phalanx of the ring finger and the palm, respectively. Meanwhile, chondrosarcoma and synovial sarcoma were common malignant tumors at the dorsal part of the hand. Local pain and painless mass were the chief complaints in patients with benign bone and soft tissue tumors, respectively. Most patients with malignant tumors were referred after unplanned resection. When patients were classified into two categories by tumor size according to maximal diameter, tumors larger than 19 mm had a significantly higher risk of malignant ( p = 0.031) despite being smaller than other tumors in different body parts. Conclusion: When a tumor malignancy is suspected, the patient should be referred to a specialist to avoid unplanned resection or delayed diagnosis due to misdiagnosis. Knowing the distribution and clinical features should help in diagnosing hand tumors.

The Relationship

We present a rare case of a lipoleiomyoma which was discovered incidentally in a hysterectomy specimen of a 74-year old female patient who underwent surgery for a biopsy proven serous adenocarcinoma of the uterus. Lipoleiomyomas represent uncommon, usually benign soft-tissue tumors, generally found in obese menopausal as well as postmenopausal women aged 50 to 70 years. The reported incidence varies from 0.03\% to 0.2\%. The relationship between lipoleiomyomas and gynecologic malignancies has only been reported in a few cases. We report this case of lipoleiomyoma due to its rarity and its association with a serous adenocarcinoma in our patient.

Background: Fine needle aspiration cytology has an established role in the diagnosis of various neoplastic and non-neoplastic lesions. Its accuracy when applied by experienced and well trained practitioners matches that of histopathology in providing an equivocal diagnosis; so it can also be used as a very useful alternative to excision biopsy in the diagnostic workup of soft tissue tumors.Materials and Methods: This retrospective study was done in the Department of Pathology, Kathmandu Medical College for a period of one year from January 2006 to December 2006. A total of 60 cases presented with soft tissue tumors, of which only 50 were biopsied and the correlation done. A detailed history, clinical findings, routine relevant laboratory investigations and radiological findings were carried.Results: Fine needle aspiration cytology revealed diagnostic materials in 47 cases and 3 cases were inconclusive for a definite diagnosis. 40 cases were diagnosed as benign lesions and 7 cases as malignant lesions. Out of the benign cases, the most common were lipomas which accounted for 52.5% of cases followed by benign mesenchymal tumor- 17.5%. Out of the malignant cases 71.42% were diagnosed as malignant mesenchymal tumor and 28.57% as malignant nerve sheath tumor. The overall diagnostic accuracy of fine needle aspiration cytology in soft tissue tumors in the present study was 86%. The sensitivity and specificity of diagnosing benign soft tissue tumors was 97.36% and 66.67% respectively and for malignant soft tissue tumors 66.67% and 97.36% respectively.Conclusion: Fine needle aspiration cytology can be effective and reliable diagnostic tool in the evaluation of soft tissue tumors. It is highly sensitive to detect benign soft tissue tumors and highly specific for malignant soft tissue tumors.Journal of Pathology of Nepal (2012) Vol. 2, 305-308DOI: http://dx.doi.org/10.3126/jpn.v2i4.6884

Mri Characteristics

Schwannomas are benign soft-tissue tumors that arise from peripheral nerve sheaths throughout the body and are commonly encountered in patients with neurofibromatosis Type 2. The vast majority of schwannomas are benign, with rare cases of malignant transformation reported. In this pictorial review, we discuss the magnetic resonance imaging (MRI) appearance of schwannomas by demonstrating a collection of tumors from different parts of the body that exhibit similar MRI characteristics. We review strategies to distinguish schwannomas from malignant soft-tissue tumors while exploring the anatomic and histologic origins of these tumors to discuss how this correlates with their imaging findings. Familiarity with the MRI appearance of schwannomas can help aid in the differential diagnosis of soft-tissue masses, especially in unexpected locations.
