Granulocytic sarcoma (GS) is a rare extra medullary solid tumour composed of immature myeloid cells. These tumours often display a greenish colour due to the enzymatic action of myeloperoxidase in the tumour cells. Hence, the term 'chloroma' was given to this lesion in 1853. GS commonly involves bone, periosteum, soft tissue, lymph node, and skin. Rare occurrences in muscle, meninges, breast, m...

A 54 year-old-woman developed papulo-erythematous lesions on her face, arms, and trunk .These lesions showed polymorphic features. (Figure 1) Biopsy revealed an extramedullary (cutaneous and subcutaneous) infiltration of poorly differentiated myeloid cells CD34+, CD68+, LYSOZIME+, MPO+, CAE-, CD3-.(Figure 2-3) The bone marrow aspiration was compatible with chronic myelomonocytic leukemia with n...

Cutaneous manifestations can occur in the wide range of internal malignancy. They can occur by metastases or local spread, direct infiltration, or a site of primary malignancy itself. Sometimes these manifestations are related with an underlying malignancy but they do not contain malignant cells as paraneoplastic dermatological syndromes. Chronic lymphocytic leukemia (CLL) is the most common le...

We present a 46-year-old female patient who is diagnosed with synchronous postirradiation sarcoma, cutaneous relapse of a previous soft tissue sarcoma, and lung adenocarcinoma. More than one malignant tumor at the same time with an accompanying relapse of a previous malignant tumor is a rare entity. A relatively young patient diagnosed with adenocarcinoma of the urethra before age 40, which is ...

According to previous reports, cutaneous myeloid sar-coma often manifests as a red nodule on the skin. We report here a patient with cutaneous myeloid sarcoma presenting with a unique skin lesion. A 71-year-old man presented with pigmented macules of one month duration. Physical examination showed multiple grey pigmented macules, 10–30 mm in diameter , on the face and trunk (Fig. 1a). His white...

We conducted a retrospective study of patients with cutaneous myeloid sarcoma, from 2 tertiary care institutions. Eighty-three patients presented, with a mean age of 52 years. Diagnosis of myeloid sarcoma in the skin was difficult due to the low frequency of myeloperoxidase and/or CD34+ cases (56% and 19% of tested cases, respectively). Seventy-one of the 83 patients (86%) had ≥ 1 bone marrow b...

Introduction. Kaposi's sarcoma (KS) usually manifests as a cutaneous disease but GI manifestation is often rare. It is associated with human herpes virus-8 (HHV-8) and seen in immunocompromised patients. In the USA, use of highly active antiretroviral therapy (HAART) has drastically reduced incidence of KS in HIV patients. Case Presentation. A 65-year-old male with human immunodeficiency virus ...

Abstract A 14-year-old boy presented with a 7-month history of nodule on the right shoulder. It was initially pink and pea-sized but developed black areas as it grew. nontender bled occasionally. He otherwise well took no regular medications. originally from Philippines, having moved to UK 2 years previously. His mother had breast cancer. This suspected be pyogenic granuloma treated shave biops...

Kaposi Sarcoma (KS) is the most common malignancy associated with Acquired Immune Deficiency Syndrome (AIDS) and is caused by Human Herpesvirus 8 (HHV 8) or Kaposi Sarcoma Herpesvirus (KSHV). In about 90% of cases Kaposi Sarcoma is associated with cutaneous lesions; however visceral disease can occur in the absence of cutaneous involvement. In the era of Highly Active Antiretroviral Therapy (HA...

Myeloid sarcoma, considered to herald the onset of a blast crisis in the setting of chronic myeloproliferative neoplasm/dysplasia, typically presents during the course of the disorder. Cutaneous involvement is uncommon and lesions on genital skin are seldom seen. We present a case of a well-differentiated myeloid sarcoma in the penile foreskin in an apparently healthy 29-year-old male presentin...
