Martorell's Ulcer: Diagnostic and Therapeutic Challenge

The Histopathology of Leg Ulcers

Ulcerations of the lower extremities are a frequently encountered problem in clinical practice and are of significant interest in public health due to the high prevalence of underlying pathologies, including chronic venous disease, diabetes and peripheral arterial occlusive disease. However, leg ulcers can also present as signs and symptoms of various rare diseases and even as an adverse reaction to drugs. In such cases, correct diagnosis ultimately relies on histopathological examination. Apart from the macroscopic presentation, patient history and anatomic location, which are sometimes indicative, most ulcers have very distinct histopathological features. These features are found in different layers of the skin or even associated vessels. In this narrative review, we discuss and highlight the histopathological differences of several types of leg ulcers that can contribute to efficient and accurate diagnosis.

Cost effectiveness of a specialist wound care service

The Burden of Wounds Study estimated the cost of wound care across the UK to be £5.3 billion, with £3 billion associated with hard-to-heal wounds. This article looks at potential cost savings of managing hard-to-heal leg ulcers in a specialist wound care service using a multidisciplinary team (MDT) approach. This unique approach includes: a consultant dermatologist; a podiatrist specialising in mobility and gait; a clinical psychologist; clinical nurse specialists; and allied health professionals from tissue viability and lymphoedema services. Bringing together specialists from supporting disciplines provides a one-stop service for the patient. We conducted a retrospective analysis (over 365 days) of wound healing in patients attending the service for management of leg ulcers with differing aetiologies, including venous and atypical leg ulceration. Many of the patients referred to the service had a long wound history, between two and nine years, with a duration up to 25 years in the most complex cases. Within this complex cohort of patients, higher levels of focused compression was required (Accelerate Strapping, Accelerate, UK) for retromalleolar ulceration and management of foot oedema needing toe bandaging or garments. Wound healing was achieved in 72% of patients across all wound aetiologies, demonstrating the impact that a specialist MDT team can have on positive healing outcomes, and which can result in cost savings to the health economy and an improved quality of life for the patient.

Accurate Noninvasive Arterial Assessment of the Wounded Lower Limb: A Clinical Challenge for Wound Practitioners

Arterial investigations are an essential part of lower extremity wound assessment. The results of these investigations assist the wound clinician to determine the etiology of the wound, predict healing capacity, and inform further management. There are a number of noninvasive testing methods available to practitioners, all with varying levels of reliability and accuracy. Clinical wound assessment guidelines give varied recommendations when it comes to lower limb vascular assessment in the presence of a wound. This leaves clinicians with little guidance on how to choose the most appropriate test, and uncertainty remains about which tests provide the most accurate information in different patient-specific contexts. Conditions such as advanced age, diabetes, and renal disease are known to affect the accuracy of some commonly used lower limb arterial assessment methods, and alternate testing methods should be considered in these cases. This seminal review discusses the reliability and accuracy of lower limb vascular assessment methods used to guide lower limb arterial assessment in the presence of wounds.

Painful Leg Ulceration in a Poorly Controlled Hypertensive Patient: A Case Report of Martorell Ulcer

Martorell ulcer is a form of lower limb ulceration, preceded by a small area of excruciating pain. It often appears as a solitary lesion on the outer aspect of the lower limb, and is primarily associated with poorly controlled hypertension and diabetes. Treatment of the ulcer involves awareness and early correct diagnosis, adequate control of blood pressure, management of infection, and wound care. We describe a 77-year-old diabetic and hypertensive woman presenting with excruciating pain in her right lower lateral leg leading to a necrotic ulcer. Serial photographs of the evolution of the lesion and eventual healing of the ulcer are presented.
