Clinicopathological spectrum of lumps and bumps on the hand: A 5-year retrospective study
Background: Diverse lesions ranging from infective, inflammatory to neoplastic can occur in the hand. Almost all lesions that occur elsewhere in the body can affect the hand as well.
Methods: This was a hospital-based retrospective study of 5 years done between January 2016 and December 2020. We enumerated the clinical and histopathological spectrum of lesions of the hand. The details were collected from the patient requisition forms and pathology records.
Results: Of the 80 cases seen during the study period, 25 (31.3%) were non-neoplastic and 55 (68.8%) were neoplastic; male: female ratio was 0.95:1. The most frequent lesions identified were ganglion cysts (n = 13), followed by giant cell tumour (GCT) of tendon sheath (n = 11). Common non-neoplastic lesions included were ganglion cyst (n = 13), pyogenic granuloma (n = 3); epidermoid cyst, fungal granuloma, pigmented seborrhoeic keratosis (n = 2 each) and cutaneous horn, molluscum contagiosum and granulomatous inflammation. Amongst neoplastic lesions, mesenchymal lesions were 49 (89.1%) and epithelial lesions were 6 (10.9%); they were GCT of tendon sheath 11 (22.4%) lipomas and nerve sheath tumours 9 (18.36%) cases each, arteriovenous malformations/haemangiomas 5 (10.2%), fibromas 2 (4.08%) and one (2.04%) case each of myolipoma, fibrolipoma, benign fibrous histiocytoma, calcifying aponeurotic fibroma and benign spindle cell tumour, palmar fibromatosis. Malignant mesenchymal neoplasms included synovial sarcoma (n = 3), epithelioid sarcoma, malignant peripheral nerve sheath tumour and high-grade spindle cell sarcoma (n = 1 each). Amongst epithelial, benign lesions were 2, malignant lesions were 4, of which 3 were squamous cell carcinoma and one was melanoma and the two benign lesions were skin adnexal tumours, of which one was a case of eccrine poroma and the other was pilomatrixoma.
Conclusions: In patients presenting with lumps and bumps on the hand, common non-neoplastic lesions included ganglion cyst and pyogenic granuloma. Amongst neoplastic lesions, mesenchymal lesions and epithelial lesions were most commonly seen
Biologic width and its importance in periodontal and restorative dentistry
An adequate understanding of the relationship between periodontal tissues and restorative dentistry is paramount to ensure adequate form, function, esthetics and comfort of the dentition. While most clinicians are aware of this important relationship, uncertainty remains regarding specific concepts such as biologic width, its maintenance and applications of crown lengthening in cases of biologic width violation. Relevant publications regarding biologic width, its violation and management were identified up to August 2011 using manual and electronic database search in Medline, Embase, Directory of Open Access Journals and Google Scholar. This review discusses the concept of biologic width around tooth and its relationship to periodontal health and restorative dentistry
