Establishing accurate symptomatology associated with novel diseases such as COVID-19 is a crucial component of early identification and screening. This case report identifies an adult patient with a history of clotting dysfunction presenting with rare cutaneous manifestations of COVID-19, known as 'COVID-19 toes'', previously described predominantly in children. Additionally, this patient presented with possible COVID-associated muscle spasticity of the lower limbs, as well as a prolonged and atypical timeline of COVID-19 infection. The rare occurrence of 'COVID-19 toes'' in this adult patient suggests that her medical history could have predisposed her to this symptom. This supports the coagulopathic hypothesis of this manifestation of COVID-19 and provides possible screening questions for patients with a similar history who might be exposed to the virus. Additionally, nervous system complaints associated with this disease are rare and understudied, so this novel symptom may also provide insight into this aspect of SARS-CoV-2., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2021.

A 42-year-old woman with a history of acute myeloid leukaemia status postallogeneic stem cell transplant presented with fevers, altered mental status, pulmonary infiltrates and septic shock that further progressed to thrombocytopenia and purpura fulminans. Laboratory studies were consistent with a diagnosis of thrombotic thrombocytopenic purpura (TTP). Blood cultures grew Streptococcus pneumoniae On chart review, our patient had a history of low immunoglobulin levels following stem cell transplant, which may have predisposed her to pneumococcal infection. The patient responded to therapy with ceftriaxone, plasma exchange, rituximab and caplacizumab. This is the fourth-documented case of pneumococcal induced TTP and, to the best of our knowledge, the first-describing pneumococcal induced TTP with purpura fulminans. We conclude that patients with TTP should be evaluated for infectious aetiologies and empiric antibiotics should be considered. Clinicians should be aware of the possibility for TTP to lead to purpura fulminans., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2020.

Digital dry gangrene is commonly seen in cases of connective tissue disease such as systemic sclerosis. In systemic lupus erythematosus (SLE) digital gangrene is rare. As initial manifestation, it is again a rare phenomenon because it occurs late in the course of disease. Here we are reporting the case of a woman who was having extensive cutaneous gangrene of her fingers and toes, as a first and foremost presentation without any other typical signs and symptoms of SLE. Her serology was positive for SLE. The patient was treated conservatively and responded well., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2019.

Peripheral limb ischaemia and gangrene are devastating complications of pneumococcal sepsis. We report a 43-year-old professional pianist who presented with early sepsis and rapid development of this syndrome. No vasopressor medication was ever administered. We urgently reviewed the medical literature on a range of therapies recommended by consulting teams, to ensure he received optimal care. Based on our review and on feedback from the patient himself, we gained valuable insights into this illness and the merits of selected treatment options. His fingers ultimately recovered their function, intact, although several toes were later amputated. More recently published reviews postulate that imbalances in coagulation factors and natural anticoagulants occur as a result of disseminated intravascular coagulopathy and 'shock liver' in the sepsis syndrome, leading to microcirculatory thromboses. We submit this report as we believe it supports this hypothesis and adds further valuable information. We hope our observations will assist other critical care clinicians confronting this serious condition., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2019.

A 62-year-old man with no pertinent medical history presented with lower extremity weakness and worsening distal fingertips and toe cyanosis/gangrene. In the outpatient setting, he was initially being treated for Raynaud's phenomenon with a calcium channel blocker. On presentation, the patient had elevated inflammatory markers and white blood cell count. Serum vasculitis panel (proteinase-3 antibody) supported the diagnosis of granulomatosis with polyangiitis. His hospital course was complicated by ischaemic stroke and a diagnosis of mononeuritis multiplex in his lower extremities. After initiating therapy with intravenous steroid and rituximab, his symptoms overall improved including cyanotic fingertips/toes. His inflammatory markers and leucocytosis also improved. Outpatient follow-up consisted of further rituximab infusions and unrelated umbilical hernia incarceration which required surgery. He was found incidentally to have subsegmental pulmonary emboli which most likely occurred during the initial presentation prior to his diagnosis. The patient moved out of state and was lost to follow-up., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2019. No commercial re-use.

Raynaud's phenomenon is a vasospastic disorder of the digital vessels triggered by exposure to cold or stress. It is most commonly observed in the hands, but also frequently affects the toes. We present three cases of patients with severe Raynaud's phenomenon in the toes, secondary to scleroderma. The diagnosis of Raynaud's syndrome and scleroderma was established according to the 2010 American College of Rheumatology and European League Against Rheumatism criteria. Patients were treated with 10 units of botulinum toxin injected into each foot. Two millilitres was injected into the base of each toe in both the left and right feet. Six weeks postinjection into the toes, patients reported an improvement of cold intolerance, colour change and frequency and severity of Raynaud's attacks. The effects were reported to last up to 5 months. To our knowledge, these are the first reported cases of the treatment of Raynaud's phenomenon in the toes with botulinum toxin A., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.

Osseous metastasis from a primary breast cancer is common, and the skeletal related morbidity is high. However, solitary acral bony metastasis is rare and the diagnosis of these lesions poses a challenge to the physician. We describe a case of a patient treated with primary breast cancer who later presented with metastatic osteolytic bone lesions confined to a forefinger and toe., (2015 BMJ Publishing Group Ltd.)

Painful legs and moving toes syndrome is rare. It is predominantly diagnosed in middle-aged adults following a history of spinal cord surgery or trauma. The syndrome consists of abnormal repetitive movements, most commonly in the lower extremities, accompanied by pain in the affected limb. Pain usually precedes the movements. We report a case in a young patient that we believe was induced by the intake of a low-potency neuroleptic, which was prescribed to him for anxiety. The patient was treated with carbamazepine with mild relief of pain and later on with botulinum injection, which significantly reduced the movements and mildly improved the pain. After stopping the treatment, the beneficial effect lasted for about 3 months after which his condition gradually returned to its initial state., (2014 BMJ Publishing Group Ltd.)

A 72-year-old man with metastatic squamous cell carcinoma of the lung presents with new lesions in the distal phalanx of right fifth finger (painful) and left great toe (painless due to long-standing peripheral neuropathy). Initially a complication of cytotoxic chemotherapy is considered and a dermatological opinion is requested. Enlargement of the lesions over the space of a week leads to plain X-ray, with findings of destruction of the distal phalanx of the involved digits confirming metastatic disease. Palliative radiotherapy is administered to decrease pain and reduce the likelihood of cutaneous and infectious complications. The patient died from systemic disease progression soon after finishing his radiotherapy. Digital metastasis (acrometastasis) should be considered by clinicians in the workup of patients with persistent digital symptoms, particularly in those with known cancer or those at high risk of cancer., (2014 BMJ Publishing Group Ltd.)

A 45-year-old man presented with a 4-day history of high-grade fever with rigours and a 2-day history of painful bluish black discolouration of extremities (acrocyanosis). He was haemodynamically stable and all peripheral pulses palpable, but the extremities were cold with gangrene involving bilateral fingers and toes. Mild splenomegaly was present on abdominal examination but rest of the physical examinations were normal. On investigating he was found to have anaemia, thrombocytopaenia with gametocytes of Plasmodium falciparum on peripheral blood smear. His blood was uncoagulable during performance of prothrombin time with a raised D-dimer. Oxygen saturation was normal and the arterial Doppler test showed reduced blood flow to the extremities. A diagnosis of complicated P. falciparum malaria with disseminated intravascular coagulation (DIC) leading to symmetrical peripheral gangrene was performed. Artemisinin combination therapy was started and heparin was given for DIC. A final line of demarcation of gangrene started forming by 12th day., (2014 BMJ Publishing Group Ltd.)

In developed countries, coagulase-negative staphylococci (CoNS) are responsible for the majority of late-onset infections in very low birth weight infants undergoing neonatal intensive care. As a common skin commensal, they are often considered as mere contaminants of peripheral blood cultures or as relatively benign bacteria clinically. We present a case of invasive CoNS septicaemia in an extremely low birth weight infant which had devastating effects.

This case illustrates a rare and unique case of a 73-year-old woman who presents with a rapidly developing digital ischaemia, superior mesenteric artery thrombus with positive-lupus anticoagulant. She then developed avascular necrosis of the femoral head. Discussion of the process of diagnosis and management of antiphospholipid syndrome and catastrophic antiphospholipid syndrome are reported.

Systemic lupus erythematosus (SLE) has rarely been reported among African blacks. However, recent reports may indicate otherwise. Digital gangrene in lupus patients has been reported in different populations and has mostly been seen in patients with long-standing lupus. Digital gangrene as the initial presentation of SLE has rarely been reported, even among African blacks. Two cases of digital gangrene as the initial presentation in Nigerian lupus patients are hereby presented. The medical and surgical managements, as well as relevant literature are hereby discussed.
