A 43-year-old lady with type 2 diabetes mellitus and bronchial asthma presented with varicella zoster infection, dyspnea, and neck fullness. An urgent computed tomography scan revealed a mediastinal abscess with superior vena cava thrombus. Blood, mediastinal pus, and swab from a vesiculopustule on the neck cultured group A beta hemolytic Streptococcus. She recovered with a combination of broad spectrum antimicrobials, antivirals, and surgical drainage. This case illustrates the rare occurrence of mediastinal abscess and acute superior vena cava obstruction caused by group A beta hemolytic Streptococcus complicating adult varicella zoster.

Cutaneous infiltration by leukemic cells is uncommon and may be associated with progression of disease. The authors present the case of a 77-year-old female patient, referred to the dermatology clinic for red, erythematous, pruritic papules, which had suddenly appeared on her left hemithorax, along the C6 dermatome, with a 4-week duration. She had already been medicated with Valacyclovir and Acyclovir for 4 weeks, without clinical improvement. She also had a diagnosis of B-cell chronic lymphocytic leukemia (B-CLL), type 2 diabetes mellitus, and multinodular goiter. Tzanck smear showed no multinucleated giant cells,and PCR testing for Varicella Zoster Virus (VZV) and Herpes Simplex Virus (HSV) on skin biopsy was negative. Histopathology showed a typical B-CLL infiltrate (CD3+, CD20+) and cytogetic analysis was compatible with alterations seen in the bone marrow, confirming the diagnosis of cutaneous infiltration by B-CLL. The patient began chemotherapy with chlorambucil and intravenous human immunoglobulin, which resulted in total regression of the lesions as well as the pruritus. Even though lymphocytic infiltration of Herpes Simplex or Herpes Zoster scars is well documented, cutaneous infiltration with a zosteriform distribution without a previous episode of herpes is very rare. The therapeutic target should be the leukemia itself.

Severe disseminated varicella zoster virus (VZV) infection rarely occurs in patients who are not recipients of hematopoietic stem cell transplantation. This report concerns severe disseminated VZV infection in a diffuse large B cell lymphoma (DLBCL) patient treated with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone (R-CHOP). The patient was an 82-year-old male with DLBCL who had a history of type II diabetes mellitus. He incurred VZV infection with severe hepatitis and disseminated intravascular coagulopathy after three courses of R-CHOP. When the VZV infection occurred, anti-VZV IgG was not detected and lymphopenia was observed. We initiated treatment with acyclovir, immunoglobulin, and thrombomodulin alpha, and rescued this patient. We suggest that the use of chemotherapy for immune-suppressed elderly lymphoma patients may involve the risk of severe VZV infection.

Ischemic stroke is a rare complication of varicella-zoster virus (VZV) infection. We present the case of a patient with a medical history of type 2 diabetes mellitus (DM) who experienced disseminated cutaneous VZV infection followed by multiple cerebral infarcts associated with VZV vasculopathy. Brain magnetic resonance imaging revealed multiple hyperintense lesions over the bilateral deep white matter and basal ganglia. A skin biopsy revealed small-vessel leukocytoclastic vasculitis with neutrophilic, lymphocytic, and eosinophilic infiltration. This case report describes the rare finding of cutaneous leukocytoclastic vasculitis in VZV infection and highlights that VZV infection is an uncommon but critical etiology of cryptogenic stroke in patients with DM.
