This clinical photograph consists of two panels (A and B) demonstrating long-term sequelae of severe burn injuries. Panel A is an anterior-view clinical photograph of a patient showing a significant post-burn neck contracture, characterized by vertical bands of tightened, shortened skin extending from the chest to the chin, causing eversion of the lower lip (ectropion). The chest skin displays extensive mottled dyspigmentation with areas of hyperpigmentation and hypopigmentation, consistent with an unstable chronic scar. Panel B is a close-up of the left chest wall and axillary region, revealing a large (approximately 15 cm x 10 cm), exophytic, fungating mass arising from the scarred tissue. The lesion presents a cauliflower-like or cobblestone texture with variegated colors indicating areas of necrosis, purulent discharge, and potential hemorrhage. This presentation is highly clinically significant for the development of a Marjolin ulcer—a squamous cell carcinoma arising within a site of chronic inflammation or previous thermal injury. The image serves as an educational tool for identifying late burn complications and malignant transformation in chronic scars.

Clinical photograph of the medial and posterior aspects of a human foot showing a large, exophytic, fungating mass and extensive scarring. The mass is localized to the posterior heel and Achilles tendon region, measuring approximately 6x10x12cm. It exhibits a heterogeneous appearance with a reddish, fleshy, and friable proximal border, while the more distal portion on the plantar heel shows a rough, cauliflower-like texture with areas of yellow-brown discoloration and suspected necrosis. An arrow points to a smaller, elevated satellite lesion superior to the main mass. The surrounding integument of the foot and distal leg shows significant chronic scarring, dyspigmentation, and texture changes consistent with prior burn injuries. This clinical presentation is highly suggestive of a Marjolin ulcer, a squamous cell carcinoma arising from a chronic burn scar. The educational focus is on identifying malignant transformation in chronic wounds and understanding the visual morphology of aggressive skin malignancies.

This clinical photograph displays a close-up view of a prominent exophytic lesion on the left tibial region. The lesion is approximately circular but possesses irregular, raised borders and a friable, non-uniform surface characterized by granulation tissue, focal ulceration, and crusting. The color is variegated, showing a mixture of erythematous (red/pink), dusky purple, and dark grey/black tones. The surrounding skin exhibits clear signs of chronic tissue change consistent with a previous burn injury and subsequent autografting, including altered pigmentation, shiny texture, and scarring. A localized zone of erythema and induration is visible immediately adjacent to the base of the mass. Clinically, this presentation is highly suggestive of a Marjolin's ulcer—a squamous cell carcinoma (SCC) arising within a chronic wound or scar. This image illustrates key morphological red flags for malignancy in chronic wounds, such as rapid growth, exophytic architecture, and heterogeneous coloration in an area of prior thermal trauma.

This clinical gross photography depicts a distal thigh- to above-knee amputation stump with a chronically scarred, ulcerated soft tissue lesion consistent with Marjolin's ulcer arising in a prior traumatic scar. The overlying skin shows hyperpigmented, leathery areas with focal induration and necrotic regions at the margin of the scar, transitioning to healthier surrounding tissue. The lesion is exophytic and crateriform, with irregular, raised borders and crusting, extending into the scarred subcutaneous tissue. In many Marjolin's ulcers, the histology reveals squamous cell carcinoma, typically well differentiated, characterized by nests of malignant keratinocytes with possible keratin pearl formation and invasion into deeper dermis and subcutaneous planes; clinically, this entity bears a latent interval of years to decades after initial injury. This image emphasizes the aggressive behavior and potential for local invasion and regional spread despite a relatively well-differentiated phenotype. Clinical relevance includes recognition in chronic wounds or burn scars, necessity of complete excision with wide margins, and evaluation for nodal metastasis. In resource-limited settings, delayed presentation is common; in developed regions, modern wound care reduces incidence but vigilance remains essential for long-standing scars. This gross finding informs surgical planning, prognosis assessment, and multidisciplinary oncologic management including possible radiotherapy or extended resection.
