“…Only a few studies and case reports evaluate the potential role of FDG PET/CT in diagnosing primary cutaneous lymphomas [ 52 – 57 ]. Several studies indicate that FDG PET/CT is more accurate than CT in detecting both cutaneous and extra-cutaneous diseases of T cell lymphomas including mycosis fungoides [ 52 – 54 ]. We have experienced a total of 8 patients with primary cutaneous lymphomas (including 2 patients of mycosis fungoides), all of which showed FDG-avid cutaneous lesions (Fig.…”

Paraneoplastic dermatoses (PD) are defined as nonspecific skin disorders which are associated with internal neoplasms, but without direct association to primary tumors or metastases. Recognition of PD and the following surveillance may lead to the diagnosis of internal malignant neoplasms including early stage ones. Accurate imaging examinations in the following searching is essential in identifying the underlying neoplasms. Since whole-body 18-fluoro-2-deoxyglucose (F-18-FDG)-positron emission (PET)/computed tomography (CT) has been widely used in early diagnosis, staging of various malignant tumors, it may play a role for detection of underlying or occult malignant neoplasms in patients with PD. However, to date, only a few reports of FDG PET/CT findings of the associated neoplasms in PD patients have been cited in the literature. The present paper shows the cases of FDG-avid associated neoplasms in patients with PD in our 10-year experience in our institute, and reviews the well-known and/or relatively common PD and their associated neoplasms, and the previously reported cases of FDG-avid associated neoplasms in these patients.

“…In general, DLBCL patients with primary extranodal disease tend to be older, have lower tumour burden and are more likely to be Ann Arbor Stage I 4. One rare extranodal presentation is primary cutaneous DLBCL, which typically manifests with papules, nodules or cutaneous tumours that have discolouration, erythema, plaques and/or ulceration 5 6. Herein we present a rare case of DLBCL presenting as an isolated subcutaneous mass without any visible skin changes and with no nodal involvement.…”

Subcutaneous mass concerning for sarcoma: a peculiar presentation of diffuse large B-cell lymphoma

et al. 2019

Diffuse large B-cell lymphoma (DLBCL) can present in a number of different ways, including as a primary cutaneous lesion or at various other extranodal sites. However, it is rare for a DLBCL to present as a clinically subcutaneous mass without visible skin changes or nodal involvement. A 36-year-old man presented with a 4×4×1 cm subcutaneous mass to his shoulder with normal overlying skin which had been enlarging over 6 months. Physical exam and imaging together made a strong case for sarcoma, and the patient underwent a radical resection. The final pathological diagnosis returned as a diffuse B-cell lymphoma (germinal centre type). The patient subsequently healed and tolerated chemotherapy well. DLBCL can masquerade as a soft tissue mass at initial presentation. If the diagnosis is not clear, a biopsy should be pursued.

“…Chemotherapy was recommended for this patient because surgery and radiotherapy were not appropriate due to the widespread skin involvement. Extensive, high FDG uptake in the skin should also be differentiated from lymphoma, 10,11 sarcoidosis, 12,13 inflammation, 14 Sweet syndrome, 15 and Grover disease. 16 Our case suggests that cutaneous angiosarcoma can present with diffuse skin involvement, and FDG PET/CT plays an important role in determining the treatment plan to avoid unnecessary surgery and radiotherapy.…”

Diffuse Cutaneous Angiosarcoma in the Scalp and Face Demonstrated on FDG PET/CT Imaging

Diffuse cutaneous angiosarcomas are rare. Herein, we reported FDG PET/CT findings of cutaneous angiosarcoma in a 59-year-old man. FDG PET/CT imaging was performed for staging, showing diffuse intense FDG uptake with an SUVmax of 19 in the scalp and face. Chemotherapy was recommended for this patient because surgery and radiotherapy were not appropriate due to the widespread skin involvement. Our case suggests that cutaneous angiosarcoma can present with diffuse skin involvement, and FDG PET/CT plays an important role in determining the treatment plan to avoid unnecessary surgery and radiotherapy.
