Delineating the Boundaries of Superficial Lymphangitis: A Retrospective Study of 11 Cases with a Review of Literature.

Background: Lymphangitis is an inflammation of lymphatic channels caused by infectious or non-infectious agents, presenting with characteristic linear erythematous streaks draining toward regional lymph nodes. Objective: To describe the clinical characteristics and etiological factors involved in acute superficial lymphangitis in a retrospective descriptive study. Materials and Methods: Records of patients were analyzed retrospectively who presented with linear erythematous streaks, diagnosed as superficial lymphangitis, in the outpatient department of dermatology during the last 5 years (January 2018-December 2022) in a tertiary care hospital. Patients were evaluated for their demographic profile, detailed history, complete physical examination, and standard blood tests (if necessary). Results: A total of 11 patients were found, out of which 7 (63%) were males and 4 (37%) were females. The mean/median age of these patients was 30 years (range 9-52 years). The minimum duration of development of lymphangitis was within minutes in the case of a mosquito bite reaction and around 72 hours in the case of trauma or infection induced, with a median interval of 48 hours. The site most commonly involved was the upper extremity in 8 (72%) patients, followed by the trunk in 2 (18%) and the lower extremity in 1 (9%). Arthropod bite reactions (63%) were the most common etiological agent. All patients presented with linear erythematous streaks extending towards draining lymph nodes. Conclusion: Lymphangitis is often considered to be a bacterial infection and is mostly treated with antibiotics; however, non-bacterial and non-infectious causes should be kept in mind while treating superficial lymphangitis to make judicious use of systemic antibiotics.

Radio-isotope occult lesion localization (ROLL) techniques to identify the clipped node for targeted axillary dissection (TAD) in breast cancer.

BACKGROUND: Breast cancer patients having neoadjuvant systemic therapy (NAST) who have a positive (clipped) lymph node (CN) at presentation must have that CN removed to assess pathologic response at later surgery. Multiple techniques for localizing the CN have been described. We describe a novel ROLL-based approach. METHODS: Consecutive patients between 2018 and 2021, having NAST with biopsy proven positive lymph node(s), had a clip placed into the most abnormal node(s). At later surgery sentinel node and occult lesion localization (SNOLL) was performed with peritumoral radio-isotope (99m Tc-Nanoscan) injected under ultrasound guidance. Planar and single photon emission computed tomography (SPECT-CT) images were used to identify sentinel nodes (SN) and the CN. If the CN was not a SN, then additional 99m Tc-Nanoscan was injected directly into the CN using ultrasound (ROLL). TAD was performed using a gamma probe and intra-operative specimen radiographs to confirm excision of the CN. RESULTS: Thirty-eight patients underwent TAD. 20/38 CNs were SNs on SPECT-CT. 17/38 CN were localized separately. 1/38 CN was not a SN and could not be identified on ultrasound. The remaining 37/38 (97.4%) of the CNs were removed intra-operatively. Pathological complete response in the axilla was identified in 18/38 cases. The CN was the only positive node in 10/20 cases. In 18/20 cases the CN contained the largest tumour deposit. CONCLUSION: Combining SNOLL and ROLL techniques to identify the SNs and, if separate, the CN for TAD is very reliable and logistically robust, especially for units already performing peritumoral lymphoscintigraphy.

Synchronous Operable Pancreatic and Breast Cancer Without Genetic Mutation: A Literature Review and Discussion.

Background: Synchronous cancers are rarely detected when working-up a patient for a primary cancer. Neoadjuvant management of synchronous breast and pancreatic cancers, without a germline mutation, has yet to be discussed. Two patients were diagnosed with synchronous breast and pancreatic cancers at our institution over the last decade. A literature review was performed to evaluate the current evidence stance. Results: The first patient was 61-years old and diagnosed with a HER2+ breast cancer. The second patient was 77-years old and diagnosed with a Luminal B breast cancer. The inability to provide concurrent breast and pancreatic neoadjuvant therapy for the HER2+ patient, resulted in upfront surgery. The second patient was able to have both cancers treated simultaneously - neoadjuvant chemotherapy to the pancreas, and neoadjuvant endocrine therapy to the breast. Discuss: There is no single neoadjuvant regimen that treats both pancreatic and breast cancer. The differences in breast cancer sub-types impacted our neoadjuvant options. Our recent experience led us to the hypothesis that breast cancer care dictates treatment, while pancreatic cancer determines survival. There is a significant paucity in the literature regarding synchronous breast and pancreatic cancer.

Breast Radiotherapy after Oncoplastic Surgery-A Multidisciplinary Approach.

Oncoplastic breast surgery encompasses a range of techniques used to provide equitable oncological outcomes compared with standard breast surgery while, simultaneously, prioritizing aesthetic outcomes. While the outcomes of oncoplastic breast surgery are promising, it can add an extra complexity to the treatment paradigm of breast cancer and impact on decision-making surrounding adjuvant therapies, like chemotherapy and radiotherapy. As such, early discussions at the multidisciplinary team meeting with surgeons, medical oncologists, and radiation oncologists present, should be encouraged to facilitate best patient care.

Case Report of 18F-FDG PET/CT Features of Polyacrylamide Hydrogel Mammoplasty.

ABSTRACT: A 57-year-old woman with a history of previous bilateral breast polyacrylamide hydrogel injection presented for 18F-FDG PET/CT imaging to investigate recurrent retroperitoneal liposarcoma. Incidental symmetrical FDG-positive accumulation was noted in the bilateral axillae tracking between the interpectoral planes. The finding is consistent with a chronic inflammatory process secondary to the migration of the polyacrylamide hydrogel injections.

Spectrum of Cutaneous Adverse Drug Reactions to Anti-tubercular Drugs and Safe Therapy after Re-challenge - A Retrospective Study.

BACKGROUND: Tuberculosis (TB) is a major global health problem and leading cause of death. Anti-tubercular therapy (ATT) can lead to various adverse effects including cutaneous reactions. Re-challenge remains the only option to restart the safe therapy with limited number of most efficient primary ATT drugs. OBJECTIVES: To study the demographic profile, identify the spectrum of cutaneous eruptions, offending drug and the reinstitution of safe ATT. MATERIALS AND METHODS: This was a retrospective study with inclusion of the indoor patients with cutaneous adverse drug reaction secondary to ATT. Hospital records were analyzed regarding demographic characteristics, type of TB, ATT regimen, pattern of drug rash, offending drugs, laboratory parameters, and reinstitution of ATT after re-challenge. RESULTS: All the cases (40 patients) were reported in adults with male to female ratio of 1:1.2 and mean age of 50 years. Pulmonary TB was the most common type of TB observed in 24 (60%) patients followed by extra-pulmonary in 16 (40%) patients. Maculopapular rash was the most common (42.5%) type of cutaneous eruptions and ethambutol, the most common (45%) offending drug followed by other first line anti-tubercular drugs. Ten (25%) patients developed multiple drug hypersensitivity on re-challenging. Multiple drug hypersensitivity was seen in 10 (25%) patients. CONCLUSION: Drug reaction to ATT is like a double-edged sword as stopping ATT and starting treatment of reaction with systemic steroids can further aggravate the condition with increased risk of disseminated and multidrug resistant tuberculosis. Re-challenge with ATT not only find out the culprit drug but also helps to restart a safer alternate ATT regimen. LIMITATIONS: Small sample size, lack of proper hospital records due to which some patients were missed and the fact that re-challenge was not performred in mild lichenoid type rash.

Dyskeratosis congenita: presentation of cutaneous triad in a sporadic case.

Dyskeratosis congenita (DKC) also known as Zinsser-Cole-Engman syndrome is a progressive genetic disease with a classical presentation characterised by a triad of reticulate pigmentation of skin, nail dystrophy and leukoplakia. It may be a multisystem disease with the involvement of haematological, gastrointestinal, genitourinary, neurological, ophthalmic, pulmonary and skeletal system. We report a sporadic case of DKC presenting with poikiloderma, nail dystrophy and oral leukoplakia.

Nipple-sparing mastectomy with implant reconstruction: the Westmead experience.

BACKGROUND: Nipple-sparing mastectomy (NSM) involves the removal of all breast tissue with preservation of the breast skin envelope and nipple-areola complex (NAC). The objective of this study was to report the outcomes from our initial experience with NSM. METHODS: We retrospectively analysed 87 women who underwent 118 NSMs between October 2008 and May 2012. RESULTS: Indications for NSM were 60 (51%) primary cancer, 15 (13%) residual/recurrent disease, 39 (33%) risk reduction and 4 (3%) benign pathology. Implant loss (n = 10) was associated with subcutaneous placement (P = 0.01), post-operative seroma and infection (P = 0.028, 0.001), skin flap necrosis (P = 0.007) and NAC loss (P = 0.027). Capsular contraction was related to adjuvant radiotherapy (P = 0.044). Local recurrence occurred in four patients, and NAC recurrence with invasive cancer occurred in one patient after a median follow-up of 30 months. CONCLUSION: Our Australian NSM series adds to the published literature supporting the oncological safety of NSM for early-stage breast cancer and risk reduction.
