Cryofibrinogenemia is an uncommon cause of intravascular coagulation necrosis of the skin and occurs as a result of vascular occlusion from cryoproteins, which reversibly precipitate in cold temperatures. The disease is associated with various conditions, most commonly neoplastic and thromboembolic diseases, and produces cutaneous manifestations such as purpura, ecchymoses, gangrene, and ulcerations. Diagnosis is based on clinical cutaneous manifestations, histopathology, and the laboratory detection of cryofibrinogen precipitation. Treatment is based upon resolution of the underlying disease process or condition, although some interventions have been reported to have therapeutic efficacy. We discuss the presentation, diagnosis, and treatment of a case of cryofibrinogenemia in a patient with underlying B-cell lymphoma.

A 65-year old man presented with acute abdominal pain and fever. The initial diagnosis was small bowel gangrene. Pathology revealed small to large abdominal vessels obliterated by cells of intravascular B-cell-lymphoma (IVL). Visceral IVL involvement is common at autopsy but rarely reported in patients with acute abdomen. The subtype of diffuse large B-cell lymphoma is a rare and aggressive malignancy, which in typical cases is characterized by cephalic or cutaneous manifestation. Few cases showed involvement of large vessels which in combination to fibrin thrombi may lead to infarction of the organ involved. Thus IVL should be considered in cases of ischemic diseases with fever of unknown origin.

Pain from pressure ulcers can severely impact a patient's quality of life. Evidence-based treatment of ulcer-related pain typically relies on systemic opioids with limiting side effects. Literature exists on the use of topical ketamine for neuropathic pain, but not for tissue injury in general and for decubitus ulcer pain specifically. Ketamine has a number of actions including blocking of the glutamate NMDA ionophore in the periphery. Preclinical evidence suggests that NMDA receptors located on peripheral sensory afferent terminals may play a role in initiating pain signaling in inflamed tissues. Topical ketamine, therefore, has the potential to provide analgesia when applied to decubitus ulcers. Here a case is reported of a 54-year-old female with diffuse large B-cell lymphoma who during a critical period in her illness experienced gangrene leading to chronic bilateral stage IV decubitus heel ulcers. The severe pain reported by the patient was poorly managed using high doses of systemic opioids and resulted in intermittent systemic side effects. Adding a compounded ketamine gel to her wound dressings twice daily over an interval of several months drastically reduced her opioid use and, more important, her pain, with minimal side effects.
