desc11 = 'Case 1 - Figure 1
Skin biopsy shows a dense lymphoid infiltrate extending from the superficial through the deep dermis to the subcutaneous tissue (H&E, original magnification X20) ';
desc12 = 'Case 1 - Figure 2
The epidermis has pseudoepitheliomatous hyperplasia (H&E, original magnification X40) ';
desc13 = 'Case 1 - Figure 3
The epidermis is focally ulcerated (H&E, original magnification X100) ';
desc14 = 'Case 1 - Figure 4
The lymphocytes are predominantly large. Small lymphocytes surround the tumor mass and focally infiltrate the epidermis (H&E, original magnification, X400) ';
desc15 = 'Case 1 - Figure 5
The large lymphocytes have dysplastic, large, folded, indented or U-shaped nuclei with dispersed chromatin, prominent nucleoli, and abundant eosinophilic cytoplasm. Small lymphocytes with somewhat irregular, hyperchromatic nuclei focally infiltrate the epidermis (H&E, original magnification X600) ';
desc16 = 'Case 1 - Figure 6
The tumor cells have a sheet-like growth pattern and numerous mitotic figures are present (H&E, original magnification X600) ';
desc17 = 'Case 1 - Figure 7
The large dysplastic lymphocytes and the small lymphocytes are CD3+ T-cells (Clone PSI, Novocastra, paraffin immunoperoxidase, original magnification X60) ';
desc18 = 'Case 1 - Figure 8
The large dysplastic lymphocytes are CD4+ T-cells (Clone 1F6, Novocastra, paraffin immunoperoxidase, original magnification X600) ';
desc19 = 'Case 1 - Figure 9
Scattered small lymphocytes are CD8+, and the large dysplastic lymphocytes are CD8 negative. Most of the small lymphocytes at the edges of the tumor mass and infiltrating the epidermis (as shown in Figure 4) are CD8+, reactive lymphocytes (not illustrated in this image) (Clone C8/144B, Dako Cytomation, paraffin immunoperoxidase, original magnification X600)';
desc110 = 'Case 1 - Figure 10
The lymphocytes are strongly CD30+ in a sheet-like distribution. (Clone BerH2, Neomarker, paraffin immunoperoxidase, original magnification X100) ';
desc111 = 'Case 1 - Figure 11
Virtually all of the large lymphocytes are strongly CD30+ with a membrane and Golgi pattern of staining (Clone BerH2, Neomarker, paraffin immunoperoxidase, original magnification X600) ';
desc112 = 'Case 1 - Figure 12
The epidermis strongly expresses epithelial membrane antigen (EMA) and the large lymphocytes are EMA- (Clone E29, Dako Cytomation, paraffin immunoperoxidase, original magnification X600) ';
desc113 = 'Case 1 - Figure 13
Some of the large lymphocytes and scattered small lymphocytes have cytoplasmic expression of the cytolytic granule protein TIA-1. (Clone 2G9, Immunotech, paraffin immunoperoxidase, original magnification X600) ';
desc114 = 'Case 1 - Figure 14
The large lymphocytes lack expression of anaplastic lymphoma kinase (ALK) protein. (Clone ALK01, Ventana, paraffin immunoperoxidase, original magnification X600) ';
desc21 = 'Case 2 - Figure 1
A mixed population of lymphocytes and histiocytes infiltrates the lobules and septa of the subcutaneous fat. Hematoxylin and eosin, 100X ';
desc22 = 'Case 2 - Figure 2
Abnormal medium size lymphocytes and histiocytes are present surrounding the adipocytes. Note the apoptotic debris within some of the macrophages. Hematoxylin and eosin, 200X ';
desc23 = 'Case 2 - Figure 3
The abnormal lymphocytes have irregular, hyperchromatic nuclei with inapparent nucleoli, and sparse cytoplasm. They rim the fat spaces and are mixed with macrophages with twisted nuclei, delicate chromatin, single nucleoli and abundant clear cytoplasm. Some of the macrophages contain apoptotic debris. Hematoxylin and eosin, 600X ';
desc24 = 'Case 2 - Figure 4
The neoplastic lymphocytes are positive for CD2. Immunoperoxidase stain for CD2, 200X ';
desc25 = 'Case 2 - Figure 5
The neoplastic lymphocytes express CD8. Immunoperoxidase stain for CD8, 200X ';
desc26 = 'Case 2 - Figure 6
Granzyme B positive lymphoma cells rim the fat spaces and are present between fat cells. Immunoperoxidase stain for granzyme B, 600X ';
desc31 = 'Case 3 - Figure 1
This clinical photograph shows a violaceous nodular lesion of the right earlobe ';
desc32 = 'Case 3 - Figure 2
In this photomicrograph, one sees a vaguely nodular lymphoid infiltrate that occupies much of the dermis ';
desc33 = 'Case 3 - Figure 3
A partially follicular nature for the lymphoid infiltrate is better-seen in this photograph ';
desc34 = 'Case 3 - Figure 4
The lymphoid infiltrate is polymorphous in this area ';
desc35 = 'Case 3 - Figure 5
Notable stromal vascularity is apparent. The lymphoid cells in this field demonstrate modest nuclear atypia ';
desc36 = 'Case 3 - Figure 6
Eosinophils are admixed throughout the infiltrate, as shown here ';
desc37 = 'Case 3 - Figure 7
Modest nuclear atypia is again evident in this photomicrograph ';
desc41 = 'Case 4 - Figure 1
Low power magnification of cutaneous follicular lymphoma ';
desc42 = 'Case 4 - Figure 2
Higher magnification of cutaneous follicular lymphoma ';
desc43 = 'Case 4 - Figure 3
CD20 stain of cutaneous follicular lymphoma ';
desc44 = 'Case 4 - Figure 4
CD3 stain of cutaneous follicular lymphoma ';
desc45 = 'Case 4 - Figure 5
CD21 stain of cutaneous follicular lymphoma. Note the tight meshworks of follicular dendritic cells ';
desc46 = 'Case 4 - Figure 6
CD10 stain of cutaneous follicular lymphoma showing strong expression ';
desc47 = 'Case 4 - Figure 7
Bcl-6 stain of cutaneous follicular lymphoma showing weak but definite staining of neoplastic B cells ';
desc48 = 'Case 4 - Figure 8
Bcl-2 staining of this case with strong expression ';
