Clinical and histopathologic features of acquired perforating collagenosis: A case report

@#A 51-year-old hypertensive and diabetic male patient, admitted due to acute kidney injury on top of chronic kidney disease, was referred to the dermatology service. He presented with a 3-month history of multiple discrete pruritic papules with keratotic plugs over the extensor aspects of the bilateral upper and lower extremities, initially managed as a case of scabies infestation but medications given provided no relief. Histopathologic analysis of a skin biopsy revealed findings of acquired perforating collagenosis. Resolution of lesions and pruritus were noted after starting on a topical corticosteroid ointment on the lesions, as well as hemodialysis to address the renal failure. Subsequent consults showed no recurrences and only a minor sequela of post-inflammatory hyperpigmentation.

Lupus panniculitis in an ANA-negative systemic Lupus Erythematosus patient: A case report

Introduction@#Lupus panniculitis (LP) is an unusual type of cutaneous lupus erythematosus (CLE) wherein the cutaneous inflam- matory reaction involves primarily the deeper dermis and subcutaneous fat. It is characterized by the appearance of recurrent, mostly asymptomatic, firm, nodules or plaques, involving the face, upper limbs, and buttocks.@*Case report@#In our case, a 30-year-old female presented with a non-tender, non-movable nodule on the left breast, 6 weeks prior to her admission. She had fever, chills, and joint pains. The patient later developed hyperpigmented plaques on the infra- clavicular area, and left flank extending to the abdomen. Urinalysis showed proteinuria, and RBC cast. She also had leukopenia, and anemia on CBC. Chest computerized tomography (CT) scan revealed a heterogeneously enhancing soft tissue mass in the base of the neck at the right infraclavicular region with malignant features. ANA titer was normal, while skin biopsy on two sites and direct immunofluorescence studies were compatible with lupus panniculitis. She was managed as a case of systemic lupus erythematosus (SLE) using a combination of hydroxychloroquine, and oral corticosteroids, which afforded temporary relief of symptoms. The patient however was lost to follow-up and opted for alternative medicine, and subsequently succumbed to the complications of SLE.@*Conclusion@#This case highlights the importance of a carefully made assessment after an accurate clinicopathological cor- relation was done. This case also emphasizes that although LP if associated with SLE may signify a milder condition, judicious monitoring and follow-up must still be undertaken since management is based on the disease activity.
