A 5-month-old Malay boy presented with purpuric papules and plaques on the face and extremities accompanied by fever, coryzal symptoms and bilateral lower limb oedema. There were also bullous linear purpuric lesions on the right upper limb. Blood and culture tests were normal. Histopathological tests showed leucocytoclastic vasculitis, confirming the diagnosis of acute haemorrhagic oedema of infancy. The patient achieved complete recovery after 2 weeks with no recurrence.

Erythema elevatum diutinum (EED) is a rare, chronic leukocytoclastic vasculitis characterized by erythematous to violaceous plaques and nodules, typically on extensor surfaces like the hands, elbows, and knees. It results from immune complex deposition in blood vessels, leading to inflammation and fibrosis. EED is often associated with infections, autoimmune disorders, or hematologic malignancies, but can also occur idiopathically. Although globally documented, EED is extremely rare in the Philippines, particularly in adolescents, highlighting its significance in local literature.

A 14-year-old Filipino female presented with a 5-month history of asymptomatic, skin-colored papules on her right elbow, gradually spreading to both elbows and knees, with occasional mild pruritus and knee joint pain. Past medical and family history were unremarkable. After temporary relief from an unrecalled cream prescribed by a private dermatologist, she was referred for skin punch biopsy, which revealed spongiotic epidermis with papillary dermal edema, moderate inflammatory infiltrates, eosinophilic inclusion bodies, and nuclear dusts surrounding the blood vessels, consistent with EED. The patient was treated with dapsone 50 mg/day, clobetasol propionate ointment twice daily for two weeks, and cetirizine 10 mg as needed for pruritus, resulting in clinical improvement.

This case highlights the extreme rarity of EED in the Philippines, particularly in adolescents. It emphasizes the need to consider EED in chronic papular eruptions and demonstrates the effectiveness of dapsone and topical steroids in managing the condition. Early diagnosis and timely intervention are crucial for preventing disease progression and improving patient outcomes, as seen in this case.

Leukocytoclastic vasculitis (LCV) is a histopathologic descriptor for a prevalent type of small-vessel vasculitis (SVV) that affects arterioles, capillaries, and postcapillary venules. Although the association between vasculitis and malignancy only accounts for <5% of vasculitis cases, it has been recognized as a true paraneoplastic syndrome in several studies. A 57-year-old Filipino male presented with erythematous, nonblanching macules on his lower extremities, which rapidly progressed to violaceous lesions on his trunk, buttocks, and lower extremities. He also reported significant weight loss, decreased appetite, and vomiting. A skin biopsy confirmed LCV. Initially treated for meningococcemia, his condition did not improve. Abdominal imaging revealed an enlarged heterogeneous liver with retroperitoneal lymphadenopathy and a parenchymal nodule. He was eventually diagnosed with vasculitis secondary to an underlying hepatic malignancy and expired later from multiorgan failure.
