Intracranial pseudolymphoma is a rare entity. We report the case of a 44 year old female who presented with headaches and was noted to have a right lateral ventricular lesion on a background history of Burkitt's lymphoma. She underwent biopsy of said lesion and was found to have benign reactive lymphoid tissue. This is the third reported case in literature of intracranial pseudolymphoma and the first reported intraventricular lesion.

Review
Immunoglobulin gamma (Ig) type 4-related disease (IgG4-RD) is a chronic immunologic systemic disorder that has gained worldwide recognition in the past decade. This entity can affect almost every organ system, and its characteristic lesions have been found in a variety of organs such as lacrimal and salivary glands, pancreas, liver, bile ducts, lungs, kidneys, retroperitoneum, breast, aorta, thyroid, and prostate. This case reports a very rare case of IgG4-RD presenting with a cutaneous lesion in a young female patient mimicking a lymphoproliferative disorder. IgG4-RD affecting the skin is a rare entity and has mostly been reported in Japanese men of middle to older age. IgG4-RD with cutaneous involvement should be in the differential of non-neoplastic, lymphomas, autoimmune, and infectious disorders of the skin.

Cutaneous pseudolymphomas are reactive lymphoproliferations. The most frequent type is nodular pseudolymphoma, and to date, their ultrasonographic appearance has not been reported. We reviewed the ultrasound images of histologically confirmed nodular types of pseudolymphomas studied with 18 and 71 MHz linear probes. All lesions were predominantly hypoechoic and presented prominent vascularity. Seventy percent of cases involved dermis and hypodermis, and 30% were only dermal. Seventy percent of cases showed internal hypoechoic globules, and 100% presented a teardrop sign, more clearly detected at 71 MHz. Ultrasound can support the diagnosis, assessment of the extent, and degree of vascularity of cutaneous nodular pseudolymphomas.

Review
This article discusses ways to recognize and manage lymphomas and pseudolymphomas associated with drug exposure. Over the last 30 years, the classification of pseudolymphomas and lymphomas has undergone significant change, especially following the application of sophisticated immunostaining and gene rearrangement analysis. The term cutaneous pseudolymphomas (CPL) is a nonspecific term for a heterogeneous group of benign reactive T- or B-cell lymphoproliferative processes that simulate cutaneous lymphomas clinically or histologically. While pseudolymphomas are relatively rare diseases, their clinical and histological heterogeneity has led to multiple systems of categorization based on immunological factors, causative agents, presentation, and clinical course.

BACKGROUND
Pseudolymphoma of the liver (Reactive Lymphoid Hyperplasia) (RLH) is a rare condition. It is usually asymptomatic and detected incidentally on radiological imaging. Imaging features are similar to hepatic adenoma, hepatocellular carcinoma, cholangiocarcinoma, and malignant lymphoma and are not specific for pseudolymphoma of the liver. Percutaneous core biopsy is insufficient to distinguish pseudolymphoma of the liver from low-grade malignant lymphoma and extranodal marginal lymphomas.
CASE DESCRIPTIONS
In this article, we present a case of hepatic RLH of a patient who was presented with a skin rash on the leg and was detected incidentally on radiological imaging.
CONCLUSION
Preoperative definitive diagnosis of hepatic RLH using various imaging methods, including MRI with hepatocellular agents, is highly difficult.
