Fine Needle Aspiration Cytology of Dermatopathic Lymphadenitis

Dermatopathic lymphadenitis in HIV

“…Melanin-laden histiocytes were not noted as reported in the earlier studies. [111] Therefore, a diagnosis of lymphoproliferative lesion was considered.…”

“…[1] Dermatopathic lymphadenitis represents a benign form of reactive lymph node hyperplasia. [2] The relationship between lymph node hyperplasia and cutaneous disease was first described by Pantrier and Woringer as lipomelanotic reticulosis.…”

Dermatopathic lymphadenitis of the head and neck

“…Immunoperoxidase staining for S‐100 and CD1a, as well as flow cytometry, were performed on previously excised lymph nodes with DL. These authors conclude that FNA findings consistent with DL can be misinterpreted as Langerhans’ histiocytosis in the pediatric population, and with low‐grade lymphoma or carcinoma in adults 5 . Biopsy of the affected lymph node may then be performed if the clinical scenario remains suspicious for either 2,3 .…”

“…These authors conclude that FNA findings consistent with DL can be misinterpreted as Langerhans' histiocytosis in the pediatric population, and with low-grade lymphoma or carcinoma in adults. 5 Biopsy of the affected lymph node may then be performed if the clinical scenario remains suspicious for either. 2,3 From the pathologists' perspective, the greatest difficulty in diagnosis of DL is its histopathologic similarity to lymph nodes involved in early-stage mycosis fungoides.…”

On the utility of fine-needle aspiration in the diagnosis of primary scalp lesions

“…21 This particular type of lymphadenitis may be seen in occipital lymph nodes as a consequence of hair dyes, and in patients with chronic itching of the scalp secondary to dander. Sudilovsky and Cha 23 and Krisnamoorthy Iyes et al 24 have published the cytologic findings, immunophenotype, and differential diagnoses of this condition.…”
